Design and build production AI agent systems for a US-based lending platform under strict data-privacy and compliance requirements. Architect multi-agent workflows with LangGraph on AWS Lambda, build RAG pipelines over multi-source knowledge bases, own observability with self-hosted Langfuse, and ship the React and Next.js interfaces on top.

Ran an independent freelance practice, delivering 25+ projects end to end for clients across the US, Europe and Latin America, reaching Level 2 with a 4.8 rating. Owned each project solo: scoping with the client, design in Figma, and implementation in Next.js, TypeScript and Astro.
