About

I am a...

Data Scientist. Applied ML/GenAI Engineer.

Builder of production AI systems, agentic workflows, and evaluation-driven products.

Over the last eight years I’ve translated ambiguous business questions into data products, ML pipelines, and GenAI systems that ship and scale.

My work spans LLMs, agentic architectures, multi-modal pipelines, experimentation, and platform delivery across UBS, EF Education First, and personal ventures.

I’m especially interested in the intersection of product strategy, rigorous evaluation, and pragmatic engineering.
