About

the person behind the terminal

Fullstack engineer with 6+ years of experience crafting performant, scalable web applications. I've shipped features to hundreds of millions of users — from live cricket scoring during IPL to equipment management flows at Deel — and I care deeply about the craft behind each one.

— Tolkien, probably, if he were an engineerTODO: replace

Known for delivering under tight deadlines, leading cross-functional efforts, and owning features end-to-end. Outside work, you'll find me watching cricket, hosting the Positive Shift podcast, or teaching frontend and system design to the next batch of engineers who'll one day outship me.

Teaching

paying it forward, every week

Beyond shipping product, I spend time every week teaching the engineers who are just getting started — the ones figuring out web, wrestling with system design interviews, and wondering if they'll ever feel like they know what they're doing. (Spoiler: you will. Sort of.)

I've been a part of Team Shiksha as an educator and community moderator — running occasional sessions, answering the same five questions about closures with genuine enthusiasm, and trying to make advanced topics feel approachable rather than terrifying.

Every Sunday

Frontend Deep Dive

A structured weekly session covering the fundamentals and internals of frontend development — how the browser works, React under the hood, performance patterns, and the things that trip people up in interviews and in production.

Every Friday

System Design Sessions

Breaking down real-world system design problems — URL shorteners, live scoreboards, notification systems — with an emphasis on trade-offs, not textbook answers. The kind of sessions I wish I'd had when I was starting out.

AlsoModerate and manage the community day-to-day — answering questions, facilitating discussions, and keeping the space one where it's safe to not know things yet.
