About

Pragmatic AI Engineer bridging the gap between technical complexity and business value. I leverage a dual background in Computer Science and Economics to identify and solve the right problems and ship production‑ready solutions on GCP and AWS.

I combine the operational rigor of Goldman Sachs with the agility of startup environments to deliver secure, scalable, and purpose‑driven AI architectures.
