I'm a software engineer based in Mumbai, India, with 3.5+ years of experience building enterprise applications — mostly in the fintech and payments space.

My interest in computers started early — a Windows XP machine at home, hours spent poking around, Winamp in the background, playing Pinball, experimenting with everything in sight. Those were fun days. It wasn't until school introduced me to my first lines of HTML that it clicked. Then came C++ in high school, and with it came bigger questions: how does a computer actually work? What happens under the hood? That curiosity carried through university, where Python and Java pulled me deeper into software engineering and I started thinking seriously about how large-scale systems are built.

Since entering the industry, I have utilized Java and Spring Boot as my primary tools for architecting robust backend systems. My early professional years were defined by designing scalable APIs, contributing to microservices development, and mastering the rigorous standards required to move code from local environments to "production-ready" states.

Today, as a Senior Software Engineer, my work centers on the banking payments domain and gateway integrations. I dedicate my time to translating complex transaction flows into backend systems that are inherently simple, reliable, and secure. I find deep satisfaction in this specific problem space, where technical precision is critical to the integrity and success of every transaction.
