Driving product strategy at scale.
From roadmap to revenue.

Full-stack builder. Systems thinker.
I write code that ships.

Same person. Two terminal windows.

I don't pick sides. I ship both.

By day, I'm a Senior Technical Product Manager at HackerRank, orchestrating developer assessment platforms that reach millions. By night (and sometimes also by day), I'm a full-stack engineer who builds everything from AI-powered pipelines to Pokemon-style portfolio games.

I've secured 25+ cloud environments at Lookout, processed 8,000 messages per minute at Worldline, and shipped AI-powered features that saved $375K annually. The secret? I speak both git commit and boardroom.

Currently exploring the intersection of AI and product — building tools that make developers more productive and products smarter.
