About
I’m a Computer Science and Business student at UC Berkeley focused on reliable software for intelligent, data-intensive systems. At Matrix Power, I built and deployed an always-on agent system as the sole engineer, with sandboxing, approval gates, retries, spend controls, and audit logs. Previously, I built financial-reasoning evaluation infrastructure at AfterQuery and led product engineering for Berkeley platforms serving more than 6,000 users. I care about rigorous evaluation, explicit failure boundaries, and turning ambiguous problems into software people can trust.
