FastAPI Jobs

I’m building a new service and need a Python-based backend that exposes a clean, well-structured RESTful API. The priority right now is user authentication—registration, login, token refresh, and secure password handling—so the code should follow best practices (hashing, HTTPS-ready, rate limiting, etc.). Here’s what I expect: • A lightweight framework such as FastAPI, Flask, or Django REST Framework—feel free to pick whichever you’re most comfortable with, as long as it stays modular and easy to scale. • Well-named endpoints returning JSON, with meaningful HTTP status codes. • JWT or OAuth2 implementation for auth, plus logout / token blacklist logic. • Unit tests and simple Postman (or similar) collection so I can verify eac...

We are building Version 1.0 of an Agricultural AI Backend (Microservices architecture) specifically for coffee tree cultivation in Vietnam. The system requires 3 core REST APIs. All API JSON outputs must be in Vietnamese. The 3 Required APIs: Pest & Disease Detection (Computer Vision): Uses YOLOv8/EfficientNet to analyze leaf photos and identify specific coffee diseases (rust, pink disease, stem cracking) with >90% accuracy. Chemical Compliance Assistant (Vision + RAG): Takes an image of a chemical bottle, uses OCR to extract text, and uses a RAG pipeline (Langchain + Gemini/OpenAI) to check against our provided allowed/banned database. Must trigger a system action payload to "lock cultivation" if banned. Yield Prediction (Machine Learning): Uses XGBoost to process rea...

I need a production-ready solution that plugs into Tally, reads and writes data seamlessly, and removes as much manual bookkeeping effort as possible for a handful of our chartered-accounting clients. The platform must cover three flows: Expense Invoices • Capture PDFs or scanned bills with OCR, push the key fields into structured tables, let a reviewer tweak anything the model is unsure about, then post the clean voucher straight to Tally. The workflow should also fetch existing ledgers from Tally so duplicate supplier names or GSTINs are never created. Sales Invoices • Our clients already raise invoices in their own software; I want those documents pushed into Tally through an API route, not by file upload. A lightweight mapping screen is fine, but the transfer itself mus...

I’m taking a full-stack web application from concept to production and the most pressing piece right now is the backend. I want the core logic, data layer, and secure user flow rock-solid before I refine the rest of the stack. Here’s what I need you to build: • Authentication system – token-based, secure password handling, social login ready if possible • Admin panel – role management, CRUD operations, clear metrics view • Dashboard – REST-driven endpoints feeding charts/tables that can be consumed by my React frontend I’m comfortable running both Django and Flask in the same ecosystem, so feel free to leverage Django’s batteries-included features where they shine and drop into lightweight Flask micro-services when speed or is...

I’m looking for a Python-based service that, when given a vn template UUID, returns all key metadata for that video template in clean JSON. The response must include (at minimum) the template’s author, usage count, name, total duration, individual footages, cover-image URL, video preview URL, like count and any other native fields that come with the source data. Every endpoint has to be authenticated, so please wire in a simple token or JWT flow that I can later swap out for my production identity provider. The API will speak JSON exclusively for both requests and responses. I’m flexible on the exact Python framework—as long as the code is readable and well-documented—but FastAPI or Flask would keep things straightforward. Deliverables • Fully work...

I have large CSV lists of addresses and I need a straightforward tool that tells me which emails will actually reach an inbox. The key requirement is deliverability testing; I’m not interested in simply catching typos—I want to know whether each address can really receive mail. Domain-level validation must be part of the logic. The script should check that MX records exist and that the domain is capable of accepting messages. If you have a proven, low-latency way to add additional checks (such as a lightweight SMTP handshake that stops short of sending a message) I’m open to it, as long as it doesn’t violate host policies or slow the bulk run noticeably. Workflow I have in mind: I drop a file (CSV or TXT) containing thousands of emails into a folder, run the pro...

I need an end-to-end solution that gives me real-time visibility over our public-facing assets and any related dark-web exposure. The work is split into two equally critical parts, so please scope your approach with that in mind: 1. ASM (Attack-Surface Management) module • Discover sub-domains and other Internet-facing assets automatically • Scan and track open ports / running services, flagging changes over time • Store historical data so trends and newly exposed services are obvious • Expose clean REST endpoints for each function (FastAPI or similar in Python preferred) 2. Dark-Web monitoring module • Crawl and scrape TOR “.onion” sites for brand, email or credential mentions • Correlate findings with the asset list from the ASM mod...

This project is a full stack system built around a vision based browser automation bot. The bot visits three target websites, fills multi-step forms on each of them using data provided by an operator, scrapes the results returned after each submission, and stores everything in a database. The operator interacts with the system through a web interface and never touches the bot or the code directly. The system has five parts that all need to be built and connected. A React frontend is where the operator submits input data and monitors what the bot is doing in real time. A FastAPI backend sits behind the frontend and handles communication between the operator, the bot, and the database. Redis acts as the message layer between the backend and the bot, passing events like run triggers, status u...

I want to turn my Alpaca account into a fully-automated day-trading machine. The core aim is simple: the bot needs to watch live market data, decide on intraday entries and exits, and execute orders through the Alpaca API with no manual intervention. Key points to keep in mind • Primary function: automated trading only; no customer support or social media extras. • Strategy focus: day trading. The bot should open and close positions within the same session, respect configurable risk parameters, and support rapid position sizing, stop-loss, and take-profit logic. • Exchange connectivity: everything will run on Alpaca for now, but clean modular code will let me extend to Binance, Coinbase, Kraken, or any other REST/WebSocket venue later. I prefer Python, leveraging...

I want a lightweight, browser-based application that automatically straightens converging verticals in real-estate photos. Accuracy of correction is the top priority; I need the result to look as if the building was photographed with a perfectly level camera. ShiftN () comes close, but often leaves residual tilt or unnatural stretching, so the new tool must be noticeably more reliable. Core workflow • User drags one or many images onto the page. • The app detects vanishing points, computes the homography, and warps each photo so the main verticals are perfectly parallel. • A side-by-side before/after viewer lets the user verify the fix. • Corrected files are downloadable individually or in a zip when batch mode is used. Key requirements 1. Accuracy first: th...

Clean, well-documented code and test coverage are a must so future iterations remain painless. Web Frontend The React application already runs in production. The next sprint centres on adding new features while simultaneously lifting the overall experience with UI/UX refinements, stronger mobile responsiveness and a refreshed visual identity that matches our brand guidelines. Mobile Apps Once the web work is ...

I need a Python-based module that hooks directly into Zoom’s REST API so I can create, update, and delete meetings, then programmatically add participants to any of those sessions. OAuth will be the authentication method, so the flow must include user consent, token storage/refresh, and revocation handling. Core expectations • Build clean, well-structured endpoints or helper classes that wrap the Zoom API calls for meeting CRUD and participant insertion. • Ensure that participant e-mails, names, and join URLs are returned so I can save them on my side. • Follow Zoom’s security guidelines when passing access tokens or PII—no hard-coded secrets, proper HTTPS requests, and server-side token exchange only. • Deliver readable, commented Python code...
