I’m building an online journal that feels like a treasured vintage diary brought to life on screen. Visitors must be able to type directly onto each page, save their notes, then move effortlessly through the book by clicking either the page itself or the numbered tabs. Visual experience • Every turn reveals a realistic flip-page animation. • As pages glide, flower petals drift and a hint of stardust trails across the spread—sometimes subtle, at key moments more dynamic, so the effect never feels repetitive yet never overwhelms. • From the final entry readers can jump back to the cover or simply return to the previous page. Technical notes This is strictly a web application, so all effects should run smoothly in modern browsers, mobile-responsive if pos...

I’m ready to move forward with full-scale project development that covers both a mobile app and its companion web application. The goal is a cohesive experience: users should be able to start a task on their phones and pick up exactly where they left off in the browser. Scope • Mobile app development – iOS and Android, built either natively or with a robust cross-platform framework such as Flutter or React Native. • Web application – responsive, cloud-hosted, sharing a unified backend and database with the mobile client. Key needs • End-to-end architecture, UI/UX, API design, secure authentication, and smooth deployment pipelines. • Clean, well-documented code and hand-off materials so my in-house team can maintain and extend the product....

Requirements: - Download real-time volume and value data from Sharekhan - Format data in CSV file - Transfer data to webpage as live feed ticker Ideal Skills and Experience: - Proficient in web development - Experience with real-time data integration - Familiarity with Sharekhan platform - Strong skills in handling CSV files and live data feeds
I need a full-stack developer (or small team) to build a lightweight delivery-style platform that skips online payments and live GPS tracking but keeps everything else that makes these apps convenient. The heart of the project is smooth user management: customers place orders, staff receive and process them, couriers mark them delivered, and I watch the whole flow from a robust admin dashboard. AI features I want baked in from day one: • A recommendation engine that suggests products or add-ons the moment a user starts an order. • A conversational chatbot that handles routine questions and gathers feedback, while also feeding the admin panel with insights I can use for marketing and service tweaks. Within user management the critical piece is flexible role assignment&mdas...
An adaptable online registration form is needed that visitors can complete and submit directly from a browser. The form must be built so I can switch fields on or off (personal, professional, even payment-related) without touching the code every time; a single configuration file or low-code interface is ideal. Input validation should follow best practices—mandatory-field checks, proper email and phone formatting, and room for custom rules later—so the data that lands in my database or inbox is already clean. A honeypot field or similar lightweight anti-spam measure will save moderation time. For now, a simple “Submit” button that posts the data to a secure endpoint and triggers a confirmation email is enough. If you prefer React, Vue, vanilla JS, or a no-frame...
I’m building an online “rental boyfriend” service that will launch first in Lucknow with roughly 300 starter profiles. The core of the job is a full-featured web (or hybrid mobile) platform that lets visitors: • Browse profiles – each with photos, personal descriptions, ratings and reviews, plus advanced filters and search so users can quickly narrow results by age, interests, location, etc. • Chat in real time – seamless text messaging, voice calls and video calls are all required, ideally using a modern stack such as WebSockets and WebRTC to keep everything snappy and secure. • Book and confirm dates – an integrated booking engine with calendar view, availability management, and automatic confirmations. A payment gateway hook is wel...
I’m ready to turn a new content-management concept into a fully-functioning web application and need a product engineer who can own the software side from first sketch to production launch. The core goal is to let non-technical users create, edit, organise and publish content through an intuitive browser interface, backed by a solid, scalable architecture. You would guide the technical vision, select the most appropriate stack, set up the database schema, craft the front-end experience and stitch everything together with clean, well-documented code. Secure authentication, role-based permissions, media handling, version control and a straightforward editorial workflow all have to feel seamless for the end user. An API layer for future integrations and basic analytics would be a big p...
My goal is to build an AI-driven inventory management application that keeps stock counts accurate to the second and helps me plan cash flow before problems arise. The core of the platform is real-time inventory tracking—every SKU, every location, synchronised automatically. Beyond the live view of stock, the system must: • run order management workflows end-to-end (receive, pick/pack/ship, confirm) • generate clear budget-forecast reports so I can see purchasing needs and working-capital requirements weeks ahead If predictive algorithms or machine-learning models improve the accuracy of those forecasts, please incorporate them. The finished software should be easy to use through a clean dashboard and expose a secure API for future integrations. Deliverables &b...

I need a developer to build a custom auction experience for a Shopify store. The required flow: 1. Customer clicks Bid on the product page. 2. No Shopify account or signup is required. 3. Customer verifies their phone number through WhatsApp OTP. 4. Once verified, they can place bids normally. 5. Customers receive WhatsApp notifications when they are outbid or win. 6.

Winner can Add to Cart, add other products if desired, then use normal Shopify checkout. The auction UI should be integrated into the Shopify theme and match the store design.

I’m gearing up to bring a brand-new web application to market and need a seasoned software-development Project Manager to guide the entire journey—from refining requirements through go-live and the first post-launch iteration. The scope covers planning, coordinating a small remote dev team, keeping stakeholders aligned, and ensuring we hit our release window without compromising quality. You’ll take ownership of the schedule, budget tracking, and risk management while running an Agile process that suits a fast-moving product launch. Expect to work with Jira (or a comparable tool) for sprint management, Slack for day-to-day comms, and a shared Confluence space for documentation. Strong communication and the ability to translate dev progress into clear business updates are...
I need my new WHMCS instance up and running right away. The job covers the complete initial installation and configuration, tailoring the theme to match my branding, and integrating any required modules so core functions such as provisioning, billing, and client self-service are ready for use. Deliverables • Clean installation of the latest stable WHMCS on my server, configured with best-practice security settings • Custom theme adjustments (layout, colours, logos and overall branding) applied and tested across main client-facing pages • Installation or activation of the modules I specify, with each one tested to be sure it communicates correctly with WHMCS Once everything is in place I’ll run a quick end-to-end test (order to invoice) before signing off, so plea...
I need a developer who knows Shopify inside-out to add an appointment-scheduling system to my store. The key requirement is reliable Google Calendar sync so every new booking instantly shows up in my business calendar and any changes propagate both ways. Here’s how I picture the flow: a customer picks a time slot on the storefront, pays or confirms (the payment workflow is already handled by my current checkout), and the slot is immediately written to Google Calendar. Staff will also need to see updates if a customer reschedules or cancels. If you already have a preferred Shopify app or custom approach that handles Google Calendar sync smoothly, I’m open to it as long as it stays lightweight and doesn’t slow page speed. Suggested apps include Cowlendar, Apntly, Easy...

I need a full intake-to-payment flow for the BlueWay Community Airport Shuttle live within 7 days. You will receive developer-level access to Simvoly, Stripe (test mode only), Airtable and Make so you can work without delay. Core scope • Build a 10-page Simvoly funnel that guides the passenger from application through approval, payment and confirmation. • Configure a Stripe subscription product at $399 per month with a hard cap of three charges per calendar quarter, and make sure the webhooks feed Simvoly and Airtable cleanly. • Import a 144-location inventory into Airtable (22 predefined fields per record) and map the application data to the right tables. • Spin up a lightweight coordinator dashboard that lets staff view incoming applications, recent payments an...
Role: Bring in clients for custom web/app/AI development projects — you pitch, we build Compensation: 100% commission-based — 20% of total project value per client landed (e.g., $10,000 project = $2,000 commission) What you're selling: Custom builds — websites, mobile apps, AI features, or whatever the client needs (not a fixed "web design package") Leads: No pre-made lead list provided — you source and bring your own prospects/network Experience level: Open to both freshers and experienced sales professionals Location: Open internationally, not restricted to India Ideal candidate traits: Strong communication and negotiation skills Existing network or ability to prospect (LinkedIn, cold outreach, referrals, etc.) Self-motivated — this is an inde...
I need a fully-functional online platform where both individual shoppers and company representatives can browse our workwear range, narrow results quickly with search and filter tools, pick the right size and colour for every garment, and place an order without friction. The site has to feel seamless on desktop and mobile, present products in a clear catalogue, and let me expand the inventory or edit details from an admin back-end. Two user flows are essential: simple one-off purchases for retail customers, and an account-based route that allows companies to organise larger or repeat orders. Please build the code so I can add further options later—such as embroidery or full order tracking—without a complete rewrite. Clean architecture, intuitive UI/UX and concise document...
I’m wrapping up a college assignment and need a small, fully responsive website built from scratch. The site will have three straightforward pages—Home, About, and Contact—styled in a light, clean palette. The Home page should greet visitors with a concise introduction and welcome message; no sliders or heavy animations, just a neat hero section and readable text. The About page can mirror the same visual style while giving me room to drop in a short bio later. On the Contact page I’ll mainly need clear space for my details; if you feel a lightweight form makes more sense, let’s talk, but keep everything minimal. Please write clean, well-commented HTML5, CSS3 (flexbox or grid), and a touch of vanilla JS only where necessary. Make sure it looks polished on ...
I’m ready to build a modern corporate website whose single purpose is to convert visitors into qualified leads. The site will consist of four core pages—Home, About Us, Services and Contact—and every design and technical choice should reinforce that conversion goal. Here’s what I need from you: • Design & Build – A clean, mobile-responsive layout that reflects our brand, loads quickly and is easy to navigate. • Lead Capture – Prominent, well-placed enquiry forms that feed straight into our CRM (HubSpot or comparable; I’m open to your suggestion). • Content Management – WordPress, Webflow or another intuitive CMS so my team can edit copy and images without touching code. • On-Page SEO – Proper meta tag...
I need a committed, full-time engineer who can confidently split the week across Shopify, .NET, and Azure/Azure DevOps work. The role is permanent, not project-based, so I’m counting on someone who can become an extension of our small agency, build for the long haul, and communicate clearly every day.

If either o...
This project entails building a clean, well-structured portfolio website from scratch with Flask and Python as the core stack. The finished site should showcase a handful of project pages, an about section, and a contact form that sends email via a simple backend route. Beyond the visible pages, I place strong emphasis on organised, readable code: follow PEP 8, group related logic in blueprints, and include docstrings and a concise README so that I (or any future maintainer) can extend the site easily. If you spot opportunities for lightweight data processing or notice bugs while you work, please roll fixes into the same repository so everything stays consistent. Deliverables: • Fully-functional Flask app ready to run with `python ` • + clear setup instructions • Wel...

I need a complete web-based platform where clients can book a “rental boyfriend” and interact through text chat, voice calls, and live video. The core flow is straightforward: customers browse curated profiles, schedule a session, pay securely, and then connect inside the site or app without ever exchanging personal contact details. Key features I want built in: • Real-time text messaging with read receipts and basic media sharing • In-browser or in-app voice and video powered by a reliable API such as WebRTC or Twilio • Calendar-style booking that locks time slots once payment is confirmed • Secure payment gateway and an escrow logic that releases funds after each session • Private profile dashboards for both clients and companions to manage...
I need a straightforward but reliable inventory program that installs on Windows workstations and keeps my stock levels accurate the moment anything moves. Real-time quantity updates and fast barcode capture are non-negotiable, because the warehouse team relies on handheld scanners for every transaction. The new system must also “talk” to our existing ERP through an API, database link, or another proven method so item masters, purchase receipts, and sales shipments stay perfectly in sync without double entry. If you have done ERP bridges before, please highlight that experience. What I expect from you: • A Windows-based application (or well-packaged web app that runs smoothly on Windows) with live inventory tracking and built-in barcode scanning workflow. • Gu...
I’m putting together a fully responsive classified-ads site built only with HTML, CSS, vanilla JavaScript, and the latest version of Bootstrap. The core flow is straightforward: • Visitors create an account or log in, then post, edit, or delete their own ads. • Every ad must surface instantly through a fast search bar plus category and location filters. • Posting is powered by a token system. Users can buy tokens through UPI and spend them to publish or boost listings. What I need from you is the complete front-end package—clean, commented source files ready for drop-in back-end wiring later. That means: 1. Polished Bootstrap layouts for the landing page, auth pages, ad listing grid, single-ad view, token checkout, and a user dashboard. 2. Modular JavaSc...
I’m ready to launch a content-driven site built on PHP (Laravel) that will publish a steady mix of long-form articles and embedded or hosted videos. The core of the job is to shape a clean, responsive front-end, wire it to a lean Laravel back-end, and give me an intuitive dashboard so I can upload, tag, and schedule posts in both formats without touching code. Social media sharing is the one must-have feature for the public side: every article page and video page should surface share buttons that pick up the post title, description, and thumbnail automatically. I’m deliberately skipping user accounts and a commenting layer for now, so the build should stay streamlined with performance and security best practices in mind, yet leave room for easy expansion later. A few specific...
I need an application to assess department performance based on various faculty achievement KPIs. Key KPIs to measure: - Research publications - Teaching effectiveness - Community engagement - Book publications - Patencies - Professional classification Ideal skills and experience: - App development - Experience with performance metrics - Data visualization - User-friendly interface design Please include relevant past work in your application.
I already have the dataset, an initial Logistic Regression model, and a rough Streamlit prototype. I now need a clean, production-ready web application that lets a student enter basic details—academic scores, extracurricular activities, and technical skills—and instantly returns the percentage likelihood that they will be placed. No login or sign-up flow is required; the interface should open straight to the form and result. Here is what is in place so far: • Data: inside /data • Training scripts: and in /src • A pickled baseline model () and a placeholder Streamlit file () You’ll refine or retrain the model with scikit-learn, tidy the codebase, and polish the Streamlit UI so the prediction feels seamless and engaging. Pandas will remain the core ...
Buscamos un desarrollador senior o un equipo pequeño para construir y lanzar el MVP de una Web App B2B enfocada en Supply Chain Planning. El objetivo no es construir desde el comienzo una plataforma empresarial terminada. Queremos poner en producción, en el menor tiempo razonable, una versión funcional para clientes reales, aprender con cada engagement y evolucionarla mediante ciclos continuos de mejora. Esperamos mantener una relación de largo plazo con el desarrollador seleccionado. Después del lanzamiento serán necesarios ajustes en preguntas, reglas, cálculos, experiencia, análisis de IA y reportes según la evidencia obtenida con clientes. El MVP debe funcionar de extremo a extremo, pero puede conservar intervenció...
I want a sample website using framer for my website building business
The application is already live on Vite/React with Supabase handling Auth, Database, Storage (with RLS), and the repo managed on GitHub. What I need now is a solid clean-up and hardening phase, not a redesign. Here is what I expect once you jump in: • Run a complete code review and resolve every bug you uncover in authentication, database interactions, the user interface, Supabase storage handling, role-based access rules, security/RLS policies, and the deployment pipeline itself. • Write and execute end-to-end tests so we can prove these fixes hold under real-world conditions. • Keep the existing design and feature set exactly as they are; only stability and reliability should change. You will work directly in the GitHub repo, using pull requests so I can follow ea...

Je souhaite faire développer une application web centrée sur la gestion. Mon besoin porte essentiellement sur un logiciel de gestion en ligne qui intègre : • Gestion des stocks – suivi des quantités, alertes de réapprovisionnement et historique des mouvements. • Gestion des clients – base de données clients, suivi des interactions et historique des commandes. L’interface devra être responsive et conviviale, avec un tableau de bord clair et des rapports téléchargeables. Je suis ouvert à la technologie serveur (Laravel, Node.js, Django, etc.) tant que le code reste propre, documenté et facilement extensible. Livrables attendus : 1. Cahier des charges fonctionnel validé....
I need a streamlined WhatsApp admin chat system that lets my support team quickly respond to customer inquiries in one place. Core features I’m looking for: • Real-time two-way messaging so we can answer questions the moment they arrive. • An easy way to pull and display each customer’s order status and recent updates inside the chat window, saving us from switching tabs. • A broadcast option limited to our existing customers, so we can occasionally send promotions without spamming new leads. The solution should connect to the official WhatsApp Business API (or an approved third-party platform) and present a clean web dashboard where multiple agents can log in, tag conversations, search chat history, and see basic analytics on response times. I’m ope...
I need a clean, modern service-based website that clearly showcases what I offer. The heart of the project is a “Services” area where each service lives on its own dedicated page—think separate URLs with tailored copy, visuals, and a clear call-to-action on every one. Here’s what matters most to me: • A visually consistent homepage that funnels visitors toward the individual service pages. • A Services navigation that feels intuitive whether the site is viewed on desktop, tablet, or mobile. • Simple content-management on the back end (WordPress, Webflow, or another mainstream CMS is fine as long as I can update text and images myself). • Fast load times and SEO-friendly structure from day one. If you have ideas for adding an About or Co...
My web application runs on Google Cloud Run and, overall, behaves as expected—except for one stubborn route that keeps returning a 404. The rest of the site renders fine, so I’m convinced this isn’t simply a deployment-gone-wrong. Here’s what I know so far: • The project is entirely hosted in Cloud Run; no App Engine or Compute Engine involved. • Only a single path triggers the error. Hitting the root or other endpoints works flawlessly. • Container logs show the request reaching the revision, yet Cloud Run still surfaces a 404 to the browser. I’d like you to jump in, isolate the root cause, and leave me with a clean, reproducible fix. That may involve checking service revisions, URL mapping, IAM or firewall quirks, health checks, Go...
