About

Most teams building AI products get stuck at the integration layer brittle pipelines, slow APIs, and systems that fall apart under real clinical or production load. I build the backend infrastructure that makes AI features actually work at scale: RAG pipelines, real-time voice agents, multi-tenant architectures, and LLM chains that hold up when it matters. At a YC-backed startup, I led a 3-person team that shipped 3 AI products from scratch an AI Scribe, Voice Agent, and Email Campaigning Platform. Along the way: 40% better system performance under load, 25% faster API response times, 45% reduction in script execution time, and a secure multi-tenant system serving multiple clinic clients simultaneously. Not prototypes. Production. I'm drawn to early-stage environments where the problem isn't defined yet and the architecture is yours to own. I think in systems not just features which means I care as much about what breaks at 10x load as what ships on Friday. If you're building something that needs AI to actually work in production, that's where I show up best.
