You will get a production FastAPI REST API with JWT auth and PostgreSQL
Top Rated
Project details
Need a clean, production-ready Python backend? I build FastAPI REST APIs with real-world architecture — not tutorial code you'll need to rewrite in 6 months.
What you get in every tier:
• FastAPI with proper project structure (routers, schemas, services, models)
• JWT authentication with secure password hashing
• PostgreSQL + SQLAlchemy ORM + Alembic migrations
• Docker + Docker Compose for deployment
• Auto-generated Swagger UI + ReDoc docs
• GitHub repo with clean README
What sets this apart: I've built FastAPI backends for SaaS platforms, AI applications, and enterprise systems. Every project follows production patterns — dependency injection, async endpoints, proper error handling, clean separation of concerns.
Standard tier adds Redis caching, Celery async task queue, and RBAC. Pro tier includes AWS deployment, GitHub Actions CI/CD, Nginx, and SSL — fully live and production-ready.

Job Success
Lahore, Pakistan - 8:10 am local time
Recent production work:
MarbleBee: AI voice agent platform for a wholesale/DTC business. Twilio for calls, OpenAI for reasoning, RAG-based knowledge retrieval, and ~20 interconnected n8n workflows handling everything from lead classification to Shopify/Etsy product sync and Pinterest publishing.
AskVideo: AI video Q&A platform. FastAPI backend, ChromaDB vector search, LangChain orchestration. Users ask questions about video content and get answers with source citations, not guesses.
Chatpaper: document Q&A system with hybrid retrieval (dense + BM25 + reciprocal rank fusion), multi-format file support (PDF, Word, Excel), and citation tracking back to source.
ALE: enterprise healthcare operations platform. Multi-tenant SaaS, JWT auth, RBAC across three role tiers, RabbitMQ-driven async workers, 35+ REST endpoints, deployed on AWS with CI/CD.
What I build:
Agentic AI Systems
- AI agents with tool-calling, memory, and multi-step reasoning (LangChain, LangGraph)
- RAG pipelines with hybrid search (ChromaDB, Pinecone)
- Voice and conversational AI with real-time processing
Backend & Automation
- FastAPI/Django backends: REST APIs, JWT auth, RBAC, async task processing (Celery, RabbitMQ)
- n8n workflow automation: webhook-driven integrations, CRM/lead pipelines, third-party API connectors
- PostgreSQL/Supabase data models, Docker deployment, AWS infrastructure
