About this gig

Need a reliable backend for your website, application, or business idea? I can help you build it from scratch or improve your existing Python backend.

I develop custom backend systems and REST APIs using Python, FastAPI, and Flask, designed around your application's requirements.

What I can build:

  • Custom Backend Development: Build the server-side logic that powers your web application.
  • REST API Development: Create APIs that connect your frontend, mobile app, or other services.
  • User Authentication: Implement secure registration, login, JWT authentication, and role-based access.
  • Database Integration: Connect and manage data using PostgreSQL, SQLite, or MongoDB.
  • Third-Party API Integration: Connect external services and integrate their functionality into your application.
  • Backend Maintenance: Fix bugs, improve existing code, and optimize API performance.

What you'll receive:

  • Clean, organized, maintainable Python code.
  • Proper database integration and API structure.
  • API documentation using Swagger UI / OpenAPI.
  • Requirements file and setup instructions.
  • Testing and revisions according to the agreed scope.

Whether you're starting a new project, need a backend for an existing frontend, or

Python developer with hands-on ML and automation experience. I've built computer vision systems, data pipelines, and custom scripts using tools like YOLOv8, pandas, BeautifulSoup, and the OpenAI API. I write clean, documented code that actually runs — and I revise until you're satisfied. Top 3% nationally in Pakistan's HEC IT Skills Test. Let's build something that works.
