What I do

Data Infrastructure

Pipelines, warehouses, lakehouses. Architected for cost, built to last.

AI & Automation

From LLM integrations to intelligent workflows. Not demos — production systems.

Consulting

Audit, strategy, architecture reviews. Find the 10x before you spend the 10x.

Why me

Technically deep

5+ years shipping data systems at scale. AWS certified. Snowflake certified. I write the code and own the architecture.

Business-fluent

Economics degree. Business school. Startup founder. I speak the language of ROI, not just SQL.

Cost-obsessed

Cut a pipeline 10x. Saved $70K on another. I find waste other people normalize.

Communicates well

Presentations, public speaking, cross-functional alignment. The work ships because people understand it.
