Backend & API Architecture Service

Resilient Microservices, Cloud Databases & Secure Integrations

A stunning user interface is useless if the server crashes under load, leaks sensitive user data, or responds with sluggish latency. I engineer resilient, scalable server architectures built for enterprise reliability.

Specializing in Node.js, Express, TypeScript, and MongoDB/PostgreSQL, I architect clean RESTful and GraphQL APIs, implement multi-tenant databases, configure Redis caching, and automate complex third-party webhooks.

Whether you need payment gateway processing (Stripe, SSLCommerz, bKash, PayPal), real-time WebSockets, or automated background queues, your backend will be secure, performant, and future-proof.

Core Highlights & Capabilities

High-throughput RESTful & GraphQL API design

Payment gateway integrations (Stripe, SSLCommerz, PayPal, bKash)
