About

I'm a full stack engineer at Lakebrains, working in a forward-deployed role. I talk to clients to understand what they actually need, then design, build and ship it myself. We're a small team, so I own features end to end, from the first conversation to production, including our EV-charging platform.

What I enjoy most is using code to solve real problems for real people: a charging station that has to stay online, a lead that shouldn't slip through the cracks, a bug that should take minutes to find instead of hours. I also care about how the result feels to use, so I design the interfaces I build.

Games got me into computers as a kid, and the puzzles in them pulled me towards maths and logic. Programming grew out of that. I'm now pursuing a Hybrid MCA at IIT Patna. Outside work, I follow F1, play chess, and enjoy first-person shooters or a new movie or series.
