FastAPI Jobs

My SaaS platform already runs on FastAPI with SQLAlchemy 2.0, Alembic, and Postgres. The foundations are solid, yet several partially built features still need to reach production-ready quality, and each change must respect strict multi-tenant data isolation. Needed Tasks Scope • Finish the outstanding endpoints and background jobs that were started but never wired end-to-end. • Keep every migration in sync through Alembic and validate that tenant-level schemas remain untouched by other tenants’ data. • Refactor any SQLAlchemy 1.x patterns that may still linger so we are fully 2.0-compliant. • Add the missing unit and integration tests (pytest) to confirm isolation, correctness, and performance before release. Acceptance Criteria 1. All new or complet...

What I need I need an experienced full-stack developer to help complete and improve SurveyFlow, a land surveying and GIS platform. The system combines a React/Vite web dashboard, FastAPI backend, PostgreSQL/PostGIS database, and Expo/React Native mobile field-survey application. The main goal is to build a reliable workflow for surveyors to collect GPS/GNSS control points in the field, work offline, synchronize data when internet connectivity returns, visualize spatial data on interactive maps, manage surveying projects and documents, and prepare professional survey deliverables. Key work includes reviewing the existing codebase, fixing backend/frontend integration issues, improving PostGIS/GIS functionality, strengthening offline synchronization, improving authentication and permission...

I’m looking for an India-based freelance developer who can dive straight into our React + frontend, diagnose the issues users are reporting, and push clean, well-reviewed fixes. The codebase is already in production, so you’ll spend most of your time tracing bugs, tightening TypeScript typings, and making sure every pull request ships without breaking existing flows. You’ll work against an API layer built with FastAPI, SQLAlchemy and PostgreSQL, deployed on AWS (ECS / Fargate, Lambda, SQS, API Gateway) and wrapped in Docker with a CI/CD pipeline on GitHub. While your day-to-day focus stays on the browser side, familiarity with the wider stack will help you understand edge-cases and spot integration problems quickly. Deliverables for each sprint • Reproduce and d...

I want to build a small, self-contained application that lets me place and manage equity trades from a single interface. At this stage I have not committed to any one platform or trading style, so I am happy to consider web, desktop, or mobile solutions and to refine the workflow together once we review your proposed stack and timeline. Core functions I need right away are: • Secure sign-in tied to my brokerage API • Real-time quotes and basic charting • Order entry for market, limit, and stop orders • A straightforward positions and P&L view If you have experience wiring APIs such as Interactive Brokers, Alpaca, TD Ameritrade, or similar, please highlight that, along with the language or framework you would prefer (for example Python with FastAPI, React + ...

I’m spinning up a production-grade content-generation platform and need an experienced Python engineer to own the build from model integration through cloud deployment. The core of the system will combine Agentic AI workflows with Retrieval-Augmented Generation, all running on Hugging Face Transformers and exposed through well-designed APIs. Here’s the flow I have in mind. A user submits a brief, the system retrieves supporting knowledge from a vector store, an agent chain crafts the prompt, and an LLM returns polished copy. Everything must be containerised, orchestrated as microservices, and pushed to Microsoft Azure—ideally AKS with CI/CD in place. FastAPI, async Python, Docker and Terraform/Bicep (or an equivalent infra-as-code tool) should feel second nature to you. ...

I need a full-stack web application that lets me create and run customised communication campaigns—very similar to the way utility companies issue bills—only across Email, WhatsApp and SMS at the same time. Core workflow • I upload customer records containing billing information, purchase history and user preferences. • The system merges this data into pre-designed templates (HTML for mail, rich text for WhatsApp, SMS text and a professionally formatted PDF). • Each customer then receives a fully personalised PDF statement plus the matching message over the chosen channels. Key capabilities • Admin console with user management, campaign management and real-time reporting & analytics. • Separate, MFA-protected log-ins for super-admins...

My algorithmic trading dashboard currently lives inside a Jupyter Notebook that I publish with Voila and ipywidgets. It works, but the look and feel isn’t where I want it to be and the notebook-based stack limits how far I can take the product. I’m now moving the whole interface to a FastAPI web application and I need a designer–developer who can craft a polished, professional, finance-grade user experience. Here is the landscape you’ll be stepping into: • Python 3.10 environment running the trading logic • FastAPI already chosen as the new backend framework • WebSocket endpoints can be exposed easily for live updates • Existing ipywidgets controls and Plotly charts that must be re-imagined, not simply copied What I’d like from you:...

I need a highly interactive web application that lets Indian citizens instantly discover every Central and State welfare scheme they qualify for. The core of the product is an AI-driven search that surfaces relevant schemes based on plain-language queries, so “student from Nagpur, OBC, annual income under ₹3 L” should immediately return the right scholarships, subsidies, and other benefits. Key interface decisions • The landing page must feel lively yet uncluttered, with language selection offered as a single, elegant dropdown. Switching between English, Hindi, and Marathi should never require extra clicks or reloads. • Real-time feedback as users type (auto-suggested ministries, categories, or keywords) will keep the experience fluid. • Results need smart...

I need a premium, modern site for Freelance Web Solutions that positions us as a go-to partner for startups needing websites. The single most important outcome is a steady stream of qualified enquiries, so every design and content decision should guide visitors toward the contact form or call-to-action buttons. Style & tone Think bold, creative visuals rather than the stiff “corporate” look—something that speaks to fast-moving founders yet still feels trustworthy and refined. Clean animations, clever micro-interactions and concise copy will help convey our expertise without overwhelming users. Audience Our ideal visitor is a startup founder or product manager who probably found us through search or a referral, skims quickly on mobile, and wants proof we can buil...
