I will build reliable api integration, backend development and automations

Your app is only as good as the backend behind it.

I am Rayyaan, a full stack developer with 5 years of experience in backend development and api integration using Node.js, TypeScript and Python. I build the server side that keeps your web or mobile app fast, secure and stable.

What I do:

• REST API development from scratch, clean and documented
• Third party api integration: Stripe, PayPal, OpenAI, WhatsApp, Twilio, shipping and CRM tools
• Authentication with JWT, OAuth and social login
• Database design: PostgreSQL, MongoDB, MySQL, Supabase
• Fixing and extending an existing backend someone else built
• Deployment to AWS, GCP, Railway or your server

Every API ships with:

• Postman collection and clear docs so any developer can use it
• Proper error handling, so failures return useful messages instead of crashing
• Security basics done right: rate limiting, validation, hashed credentials

Have a frontend that needs a backend? A mobile app that needs an API? Two systems that refuse to talk to each other? That is exactly what I do.

Message me what you are building and I will send you a clear plan and quote before you order.
