I've built production web products at Basis and CodeGPT, from data-heavy dashboards and accessible React components to real-time AI chat experiences across web and developer extensions. At Basis, I improved large-table responsiveness by implementing TanStack Table virtualization.

At CodeGPT, I helped migrate the core platform to Next.js and Supabase, built streaming and WebSocket-based APIs with Deno.js, and worked with PostgreSQL, Redis, pgvector, and embeddings.
