What I'm looking for

I'm looking to build practical AI-powered products in a high-ownership environment where engineering, product, and business teams collaborate closely.

At Curai Health, I architect and deploy production AI applications using RAG, LLM workflows, retrieval systems, and full-stack architectures to bring healthcare AI capabilities from prototype to production.

Previously at Avalio and Gladly, I built multi-tenant SaaS platforms, backend services, APIs, authentication systems, and data-driven customer experience software using GraphQL and PostgreSQL.

I’ve spent 10+ years shipping reliable web products, from high-traffic React applications at The Krazy Coupon Lady to scalable AI-powered systems for distributed teams.
