I need a small, self-contained resource pack for Minecraft Java Edition that will be used on a Fabric server. Very important: This project must NOT use OptiFine, Custom Item Textures (CIT), or any client-side mods. I want this to work using vanilla mechanics only. The goal is to replace the standard carved pumpkin model with several alternate 3D fantasy-style models (for example: a long wizard’s hat, a trophy helm, and other creative variants). Players should be able to switch between these models simply by renaming the carved pumpkin in an anvil. No OptiFine, no CIT Resewn, and no external mod dependencies should be required. The solution must rely purely on vanilla-compatible resource pack features. This pack is focused and lightweight. I only need: Custom textures Cus...

On delivery I will need: • Production-ready builds for all three platforms • Source code with clear comments • A brief deployment guide and user manual • One round of post-launch bug fixes within a reasonable timeframe Feel free to recommend the most suitable tech stack—whether that’s .NET, Java, PHP, React, Flutter or any other combination—as long as it meets the goals above and...

Multi-Vendor E-commerce Marketplace (Amazon-style MVP) — Angular + Spring Boot + AWS Project Overview I need a developer (or small team) to build a multi-vendor e-commerce marketplace similar to Amazon (MVP version). The platform will support Buyers, Sellers, and Admin roles with separate dashboards. Tech Stack Requirements Frontend: Angular (responsive web app) Backend: Java Spring Boot Database: MySQL or PostgreSQL API: REST APIs Auth: JWT Authentication + role-based access (Buyer/Seller/Admin) Payments: Stripe or Razorpay Image Storage: AWS S3 (or similar) Deployment (AWS required): Frontend: S3 + CloudFront Backend: Elastic Beanstalk (or ECS Fargate if you prefer) Database: RDS (private, not public) Core Features (MVP) 1) Buyer (Customer) Features Authentica...

My multi-app food-delivery platform (React Native front ends, Java & Spring Boot backend) already runs smoothly for customers, restaurants, delivery partners and admins. I now need a secure hand-over confirmation flow: 1. When the delivery partner clicks on GET DELIVERY LOCATION, the Customer app must auto-generate a single-use OTP/Pin. 2. The code stays valid for exactly 30 minutes (time-based expiry) and the customer can trigger a fresh code immediately if something goes wrong. 3. The Delivery Partner app prompts for this code on arrival; on successful match the backend records “delivered” and releases any pending status updates to the Restaurant and Admin apps. SECOND PART: After confirmation for order from Restaurant app, all devices of DELIVERY Partner get...

...notifications and emails ahead of due dates, at custom intervals we define. Although I am open to adding payment gateways or history tracking later, this first release only needs the reminder workflow working flawlessly. I expect a clean, modern UI, role-based access for admins, teachers and parents, and secure, well-documented code. Feel free to use the frameworks you trust most for Android (Kotlin, Java or even Flutter as long as the final build targets Android), and any stable stack for the web dashboard. Deliverables: • Android APK + source code • Web admin panel with hosting instructions • Structured database schema and dump • Brief user manual and developer setup guide If you have built something similar, share screenshots or a short demo link...

I have a sizeable Java-style .properties file—roughly 1,100 English words—that needs to be rendered into standard German while preserving every bit of its structure. All comment lines appear in green and must remain in English; the only content you should touch is the white text that follows each “=”. A few technical points matter: • Back-slash line breaks () must stay exactly where they are so my application still parses the file correctly. • Keys, punctuation, and spacing on either side of “=” cannot shift. • The finished file must come back to me as a clean .properties file ready to drop into the codebase—no extra encoding issues or changed end-of-line characters. If you are comfortable handling resource bundl...

I’m putting together a quick proof-of-concept that talks directly to Tuya’s Cloud API and controls a Wi-Fi smart lock. The PoC only needs to run from the command line; no UI, no bells or whistles—just clean Java code that logs every request and response in plain-text so I can see exactly what’s happening under the hood. Here’s what the program must do, in sequence: • Authenticate with Tuya Cloud using my API Key credentials. • Create a temporary password on a designated lock that is valid for exactly one hour (now → now + 1 h). • Immediately fetch and print the list of existing temporary passwords so I can confirm the new one is present. • Delete that same temporary password and verify its removal. I can supply Tuy...

I need a dedicated software developer to build a polished Android mobile application from the ground up. I already have the core concept and basic feature list sketched out; what I’m missing is an expert who can translate that vision into clean, efficient Kotlin / Java code, craft an intuitive Material-compliant UI, and guide the app right through to a signed Play-Store-ready build. Here’s what success looks like to me: • A fully functional Android app that runs smoothly on current OS versions and common screen sizes. • Well-structured source code pushed to a private Git repository with clear commit history and inline comments. • Lightweight technical documentation (set-up steps, build instructions, and an API overview if external services are used)...

...Zygisk + LSPosed Goal: Force a USB UVC external camera to behave as the ONLY usable system camera. Requirements: Any app requesting a camera must open ONLY the external USB UVC camera.

Implementation must be done via: LSPosed module (Java hooks) Native Zygisk module (C/C++) Delivered as a Magisk module ZIP REQUIRED FINAL DELIVERABLES To be eligible for selection, submission MUST include: Working LSPosed module (APK) Working Magisk module ZIP including native Zygisk (.so arm64) Source code for both modules Clear installation instructions Demo video showing: Camera apps only open UVC Internal cameras are...

I have a freshly-created React Native project that refuses to build on my Windows development machine. Gradle fails during the Android build step, so the app never reaches the Android Emulator. I’m using Android Studio “Otter” alongside the standard Android Emulator and current Java JDK. Here’s what I need from you: • Inspect my current environment remotely (screen-share or a quick pair-programming session). • Identify and resolve the Gradle errors that block the build. • Verify that the project compiles, installs, and launches in the Android Emulator without warnings. Help me with apk generation. • Leave me with clear, step-by-step notes so I can reproduce the setup if I reinstall or move machines. A background in React Native CLI ...

...changes inside the UI. I2S handling can follow later, but rock-steady I2C comes first. You may choose any practical route—GPIO lines available on an Android SBC, a USB-to-I2C bridge, or another proven method—so long as it runs on a stock Android build. I can supply the amplifier’s data-sheet and register map as soon as the project starts. Deliverables • Full Android Studio project (Kotlin or Java) with clean, well-commented source • Working APK that finds the amplifier at its I2C address, reads/writes at least one test register, and visually reflects the change • Remote key handling that reliably adjusts an on-screen EQ parameter • Brief setup document covering hardware hookup, build steps, and pointers for adding future I2S support...

In java based architecture applications, we have used Backend Dropwizard framework (Jetty) instead of it, we have to replace it with Backend Spring Boot framework Also, in this application, we have to replace foundationDb database with Apache Cassandra instead of it. migration plan (Dropwizard → Spring Boot + FoundationDB → Cassandra + Redis + RabbitMQ ) WebSocket layer logic in the Messenger application. now it is used instead → Elixir → (gRPC Request over UDS) → Spring Boot (Client → Phoenix → gRPC → Spring → Cassandra) 1) Load Balancer HAProxy Spring Boot skeleton + Cassandra setup + data migration scripts 2) Replace Dropwizard routes/controllers → Spring Boot REST endpoints, integrate Redis/RabbitMQ 3) Elixir/Phoenix WebSocke...

...within that the priority feature is real-time performance metrics that update without a perceptible lag. From there, you’ll wire in Monaco (with C++ and Java language services) and stream submissions to Judge0 so students see compile-and-run results instantly. Once the learner experience is rock-solid, we’ll extend the same design language to a TPO Dashboard that lets placement-office staff monitor cohorts and manage interview-style sessions; state persistence for those long sessions is critical. Deliverables I’m expecting: • High-performance frontend hooked to Supabase auth/DB • Monaco editor embedded, themed, and configured for C++ & Java • Live Judge0 integration for compile/run feedback • Student dashboard with zero-lag...

I need a skilled Minecraft Java Edition admin to build and configure a 20-slot server dedicated to custom water-bucket challenges. Scope • Design a linear set of drop arenas that start simple and ramp up to nearly impossible, aligning with my “Hard to Almost Impossible” preference. • Configure game rules, world settings, and checkpoints so each stage feels progressively tougher without glitches or unintended shortcuts. • Set up precise permissions: I stay in Creative mode at all times, while every other player joins in Survival by default and can be switched to Spectator when eliminated. • Install and tweak any lightweight plugins or command-block scripts needed for smoother resets, timed attempts, and leaderboard tracking. • Walk me...

I’m migrating an older Java backend—built on legacy Spring and Hibernate—into a fresh Spring Boot 3 project so the stack is fully modern and future-proof. The focus is code refactoring: untangling dated patterns, replacing XML configuration with annotations, adopting Spring Data JPA, and cleaning up any deprecated API usage. No new features are needed right now; the goal is pure code modernization. You’ll receive a private Git repo containing the current application and a lightweight skeleton for the new one. Work incrementally, push frequent commits, and raise pull requests so the migration stays transparent and reviewable. GitHub Actions is already wired, so every PR should keep the build green. Deliverables • A runnable Spring Boot 3.x application t...

...function is a clear, intuitive snack-selection menu. The flow is simple: users open the app, browse categories or search directly, tap an item, and add it to a lightweight cart. At this stage I am not including in-app payments or review screens, so your effort can stay focused on perfecting the menu experience, item imagery, and quick navigation. Key points to cover • Native Android build (Kotlin or Java—whichever you are faster with) • Simple, modern UI that fits Material 3 guidelines • Category filter, search bar, and product detail pop-ups with image, price, and short description • Local data storage or a small Firebase/SQLite back-end so items can be updated without a new APK push • Clean, well-commented code and an APK for testing S...

I have an existing Java Swing frame that lists data in a JTable. I’d like you to extend that frame (no full refactor) so it keeps the first three legacy columns exactly as they are and adds two new checkbox columns: one for single-select, one for multi-select. Behaviour to build • Load: merge the current GET call with a specific stored procedure I will supply, then set the two new checkbox flags as the rows arrive. • Filters: the small header text fields already present must filter with strict AND logic; results should affect only the rows currently visible in the table. A separate global search box should apply the same AND logic across all visible columns. • Header checkboxes: when a user clicks the checkbox in either new column’s header, toggle t...

I need a Java developer to wire my existing trading platform directly into Interactive Brokers’ Trader Workstation (TWS) so I can operate both Individual and Business accounts from the same codebase. The goal is a production-ready bridge that logs in, streams data, and routes orders with the reliability expected of live trading. The freelancer will integrate Interactive Brokers (IBKR) TWS/Gateway API into the Mansa Bentley trading platform, enabling: Market data ingestion (equities, options, futures) Order execution (market, limit, stop) Account & portfolio management Config‑driven orchestration (YAML/JSON) FastAPI endpoints for all IBKR functions GitHub‑based project management, CI/CD, and documentation The integration must be modular, production‑ready, and fully ...

I’m ready to turn my store concept into a fully-functional Android application.

I need a small, self-contained service that can ask Google Play Integrity for a fresh device token whenever my backend re...with Google, and return the token in a secure, well-formed JSON response. • The endpoint must scale for burst traffic but a single-instance Docker image is fine to start. • Clear README covering setup, required Google Cloud credentials, and a short curl example are part of the delivery. • Any language is welcome as long as it is mainstream and has solid Google client-library support (Kotlin, Java, Node.js, Python, Go all acceptable). Acceptance I will spin up the container with my own service account, hit the endpoint, and verify I get a valid, fresh token for a new test device. If the token verifies with Google Play Integrity checker, t...

I need an experienced Android developer to turn my concept for a Utility/Tools application into a polished, ready-to-publish APK. What I’m after • A clean, well-structured Android codebase written in Kotlin or Java. • An intuitive UI that follows current Material Design guidelines. • Core utility features implemented exactly to spec (I will share wireframes and user stories once we start). • Basic analytics, crash reporting, and in-app update handling. • Clear build instructions so I can compile the project locally. I’ll handle all artwork and copy; I just need you to integrate the assets and ensure everything runs smoothly on recent Android versions. Regular progress updates through Git or a similar repo are important to me, and I&...

I need a Java developer who already knows their way around the Toshiba TCxSky ACE POS platform. The immediate goal is integration with other systems so the store data can move cleanly in and out of the POS. Depending on how the rollout unfolds, this may touch Inventory management, Payment gateways, or even CRM systems, but for the first milestone I want the core integration framework in place and demonstrably stable. Please show me past work that proves you have handled similar Java-based integrations—especially anything involving retail, POS APIs, or middleware such as XML, REST, or SOAP services. Screenshots, short code snippets, or links to live environments are all helpful. If you have tackled TCxSky or older Toshiba/IBM POS stacks before, highlight that up front. ...

I’ll be available for quick turnaround on questions and will test each milestone as soon as you deliver the build....

I will give you a working Android application that I own the rights to and need it rebuilt from the ground up. All screens, flows, wording, colours, animations and behind-the-scenes logic must match the reference exactly, so a user moving between the two apps notices no difference. You are free to use Kotlin or Java in Android Studio as long as the finished code is clean, well-commented and ready for future updates. If the original app relies on a simple server or local database, mirror that structure; if it calls external APIs, point the new build to the same endpoints. I will supply any keys or assets you need. Deliverables • Complete Android Studio project with source code • Release-ready APK (and, if possible, an App Bundle) • Brief build/run instructions so...
