about me

I'm a Senior GenAI Engineer with over 3 years of experience taking AI from idea to production inside real businesses. I embed with business teams and turn their processes into governed AI workflows and agents that people use every day.

I build agentic systems end to end: multi-agent workflows, vector and graph RAG pipelines, evaluation, observability and automated release pipelines. I ship them on LangChain, LangGraph, Azure, Google Cloud and Microsoft Copilot Studio, inside full-stack products in Python, TypeScript and React.

I engineer AI-natively. My own development runs on an orchestrated Claude Code setup, with routed agents for planning, implementation and adversarial review, gated by explicit approval steps. I also guide platform choice and governance, having evaluated Microsoft Copilot, Claude Enterprise and Agentforce for an enterprise rollout.
