About
Data and AI work with product sense.
I am a Data and AI Engineer with more than ten years of experience solving data platform problems, shaping technical direction, and connecting engineering work to product and business outcomes.
I care about the small things in big data and AI: observability, evaluation, testing, naming, ownership, and handoff quality.
I enjoy client-facing work where engineering judgment, product context, and clear communication all matter.
I lead by making technical tradeoffs visible, helping teams align, and mentoring people as they grow into stronger data roles.
