I specialize in designing REST and GraphQL APIs with Node.js, Express, and MongoDB. My approach starts by defining your endpoints, authentication needs, and integrations. I then build clean, secure, and scalable APIs with role-based access, robust error handling, and complete documentation.
I can integrate Stripe, Google APIs, messaging services, or any third-party tool you need. Each API is fully tested and optimized for performance. Finally, I handle deployment on AWS, GCP, or Vercel with CI/CD pipelines for smooth scaling. You’ll get production-ready APIs that are secure, well-documented, and ready to power your application.

Rawalpindi, Pakistan - 2:29 am local time
Most software development projects fail or require an expensive complete rewrite within 6 months because they were built on fragile architecture. I build production-ready, scalable web applications with clean, maintainable code designed to grow with your business.
As a Top Rated Full Stack Engineer with over 8 years of experience and $100K+ earned on Upwork, I bridge the gap between complex Full-stack architecture and real business value.
