About
Built for ownership, not handoffs.
Founding engineer with 3+ years of experience owning products end to end, from zero to production. At AfterBoards I identified that IPMAT/CUET students had no reliable exam practice platform and that manual exam creation was blocking the content team for multiple days per test. I built the full solution solo. Two EdTech platforms. AI pipeline that cut exam creation from days to 30 minutes. 2000+ exam attempts. 1000+ registered users.
