About this gig

Need a backend with AI built in delivered fast?


I build production-ready REST APIs using Python FastAPI 

and Node.js, with real AI integration: OpenAI, ChatGPT, 

custom LLM pipelines, and smart endpoints that actually 

do something useful.


No bloated frameworks. No spaghetti code. Just clean, 

documented, scalable backend delivered in 4872 hours.



WHAT I BUILD:

FastAPI or Node.js/Express REST API

OpenAI / ChatGPT API integration

JWT authentication & user management

PostgreSQL or MongoDB database setup

Async tasks & background job processing

Docker-ready, deployment-friendly code

Swagger UI + Postman collection included



Whether you need a quick MVP backend or a full 

AI-powered API I write clean, commented code 

your team can maintain and scale.


Source code always included

Detailed code comments on every project

Fast delivery most orders done in 48h

Free bug fixes 3 days after delivery

If you need a clean backend API — or want to plug AI into your product — I can build it in Python. I specialize in FastAPI, PostgreSQL, and OpenAI API integration. Real projects built from scratch: → Real-time Weather API with caching and structured JSON → OpenAI Chatbot backend with session history and token management → JWT-authenticated Task Manager with full CRUD and relational DB I work best with startups and solo founders who need backend work done right. Message me — let's talk about what you're building.
