What I'm looking for

I'm looking to build user-facing products and shared platform systems where I can prototype, validate with real users, and scale proven ideas into reliable production experiences.

At Quizlet, I built real-time collaborative study sessions that increased user session time by 17%, optimized high-traffic APIs across 5.3M monthly requests, and created shared API-first infrastructure adopted by five-plus product teams. I ship end to end—from controlled rollouts and experiments to production systems using React, Next.js, Node, PostgreSQL, and Redis.

Previously at Fohr, I solo-built a white-label subscription platform that reached $1,000 MRR within three months at 99.9% uptime and delivered analytics and ambassador tooling for enterprise clients. I also build independent products, including VOA, an on-device macOS AI meeting transcription app.
