I build scalable full-stack systems for AI, fintech, healthcare, and Web3 products.

I've built and scaled full-stack products at Anthropic, OPUS, Hinge Health, and Bloomreach, from Claude-powered internal tools that improved productivity by 40% to music-streaming APIs serving more than 1 million monthly active users.

I own systems end to end, designing React and TypeScript frontends, Python and Node.js services, real-time APIs, data pipelines, and cloud deployments. I improve performance through caching, async processing, indexing, and microservices, and I enjoy mentoring engineers through reviews, pairing, and design discussions.
