I built an AI powered API generator with FastAPI, PostgreSQL, Groq and Railway

I've been learning backend development and built this project to practice

real production concepts.

What it does

• Generates FastAPI code from a text description using Groq (Llama 3.3)


• Saves, versions, and exports generated code as .py files


• Pagination, search, and soft delete on generation history


• JWT auth, RBAC, rate limiting, Redis caching, background tasks


• Deployed on Railway with PostgreSQL

Tech Stack

• FastAPI


• PostgreSQL


• Groq AI (Llama 3.3)


• Redis (Upstash)


• Railway


• Docker

I'm still learning so any feedback on code quality or architecture is welcome
