About Me

Saurabh Singh

I'm Saurabh Singh, a full-stack developer passionate about turning complex problems into clean, production-ready software. I live and breathe the MERN Stack.

My specialty is payment gateway integration — Razorpay, Stripe, PayU, and PayPal. I've built transaction flows, webhook pipelines, subscription billing, and reconciliation engines for high-traffic platforms.

I'm also a committed AI integrations engineer, wielding OpenAI, LangChain, and the full suite of modern AI tools to build intelligent automation that gives businesses real leverage.

I believe in clean code, performance-first architecture, and shipping things that users actually love using.

3+ Years of Experience
9+ Live Projects
5+ Payment Gateways
