About this gig


Need a reliable backend developer for your project?


I'm a Python backend developer with 6+ years of experience building scalable APIs, backend systems, and data-driven applications.


I mainly work with FastAPI, Django, and Flask to build clean, fast, and production-ready backends.


What I can help with:

  • FastAPI for high-performance async APIs
  • Django for secure and scalable full stack web applications
  • Flask for lightweight backend services
  • Database design & optimization (PostgreSQL, MySQL)
  • API integrations and backend logic
  • AWS service integrations (S3, SES, EC2, Lambda, RDS, etc.)
  • AI integrations (OpenAI, Gemini, Claude, LangChain, RAG systems)
  • Docker setup and deployment
  • VPS / cloud deployment (AWS, DigitalOcean, Linode)


I focus on writing clean, maintainable code and building systems that scale properly.

If you need someone reliable to build or improve your backend, lets talk.


Note: Time & Cost depends upon the complexity of the project. Before put order please contact me
