Backend & Integrations
API Development & Integration Services in Pakistan
Architecting secure REST APIs, database models, real-time systems, and integrations for Stripe, MAIB, OpenAI, and other platforms.
Start a projectOverview
I design and build secure REST APIs and the database architecture behind them, along with real-time systems and third-party integrations. This includes payment gateways (Stripe, MAIB), AI/LLM APIs (OpenAI), and real-time communication (Socket.io).
The focus is on API design that stays decoupled from any one provider, so swapping or adding a payment processor or integration later doesn't mean rewriting the domain logic — an approach documented in the payment-gateway abstraction work covering Stripe and MAIB.
What's included
- • REST API design and database architecture
- • Payment gateway integration (Stripe, MAIB, and regional providers)
- • AI/LLM API integration and RAG pipelines
- • Real-time systems with Socket.io and WebSockets
- • Authentication, authorization, and API security
Tech stack
- Node.js
- Express.js
- Socket.io
- Stripe
- OpenAI API
- MongoDB
- PostgreSQL
