$ whoami

I build data systems that hold up under regulatory scrutiny — then apply that rigor everywhere else.

Eight years designing and running production pipelines, data lakes, and cloud migrations on Azure and Palantir Foundry. Twelve-plus years working specifically with claims and risk data. I'm not a healthcare specialist — I'm a data engineer whose standards were set in environments where "close enough" isn't a valid answer.

what i do

pipelines & lakes

Production data pipelines and lake architecture in Python, SQL, and PySpark — designed for correctness and lineage, not just throughput.

cloud migrations

Legacy and on-prem systems moved to modern cloud-native platforms on Azure (Data Factory, Synapse) without breaking downstream consumers.

regulated data modeling

Payment, claims, and risk data modeled at production scale, where a schema mistake has compliance consequences, not just a bad report.

automation & tooling

Internal tools and automation that remove manual steps from a pipeline — built the same way whether it's for an enterprise client or my own infrastructure.
