About Me

I’m a fullstack engineer with a strong focus on building scalable systems across web, mobile, and cloud infrastructure. I work across the entire product lifecycle from system design and backend APIs to frontend interfaces and deployment automation.

Over the past few years, I’ve built and contributed to multiple production systems involving authentication flows, wallet-based transaction systems, real-time communication features, and cloud-hosted services on AWS.

My strength lies in connecting product thinking with engineering execution, designing systems that are not just functional, but reliable, scalable, and ready for real users.

A short walkthrough of my work, systems, and engineering approach.
