About Me

Engineering Systems That Scale

I'm Rohail Ahmed, a Senior Full-Stack Engineer with 3+ years of hands-on experience designing and shipping production-grade systems. I don't just write code — I architect the full stack: from database schemas and API contracts to CI/CD pipelines and cloud infrastructure.

My technical foundation is built on Next.js, NestJS, TypeScript, and PostgreSQL/MongoDB. I've designed multi-tenant SaaS architectures, engineered real-time event-driven systems with WebSockets, built role-based access control layers, and integrated third-party payment gateways — all with a focus on reliability and long-term maintainability.

My work spans ticketing platforms processing thousands of transactions, government web modernization, 3D web applications using Three.js, and enterprise billing systems. I thrive at the intersection of product thinking and engineering rigor — understanding why a system needs to be built is as important as knowing how to build it.
