Six months at a stealth-mode edtech startup in San Francisco, split between engineering and product.

I redesigned the core web modules, which improved front-end performance by about 40%, and built the SaaS mentor-student matching flow that lifted matching efficiency by roughly 50% while holding 99.9% uptime.

Stealth startups are a strange education: you ship fast, nobody outside can see your work, and the product might pivot next quarter. What survives is the habit of building things properly even when no one is watching.
