About

Two years ago I didn't have a single shipped product or a LinkedIn follower worth counting. Now there are two startups, ₹20L+ in revenue, 1M+ impressions, and a hackathon trophy I still don't quite believe is mine. I'm a builder based in Bengaluru. Right now that means running Defellix (court-admissible contracts so freelancers stop getting ghosted on payment), after cutting my teeth as an SDE at CybraneX and CTO at Aasta. Some of the proof: TiE-U Bengaluru and an AWS PartyRock hackathon win, a 4-city hackathon I directed that pulled in 8,000+ registrations, and DevItUp crossing ₹20L+ revenue in its first 9 months. That's basically the loop I'm stuck in: ship something, see what breaks, write about it honestly, and do it again. Most of that happens in public, numbers attached, mainly so other student founders in Bengaluru can skip a few of my mistakes. Off the clock, I'm still a little bitter that Excel beat my team in a hackathon once. I write about building in public, startup execution, and what it actually looks like to go from zero to shipped as a student founder. If you're building something similar, or just want to compare notes on what broke this week, send a message, or jump into the comments on my latest post.
