Lab

Experiments that become useful software

AI WORKFLOWS

I build AI systems that data into useful product experiences. The focus is on retrieval, reasoning, evaluation and interfaces that make the model easier to trust.

PRODUCT PROTOTYPES

I move early ideas into working software quickly that can be tested before they become full products.

DATA SYSTEMS

I design pipelines and prediction workflows that collect, process and explain data clearly. The goal is simple: make raw signals useful for decisions, automation, and product feedback.
