Data and AI: where business becomes intelligence.

I believe data exists to solve real human problems. I blend operational insight, technical analysis and AI to drive better decisions.

Applied data engineering

SQL, PostgreSQL and modeling to turn raw data into a reliable foundation.

Analytics & visualization

Power BI, Metabase and Python to reveal patterns, anomalies and opportunities.

Artificial Intelligence

Generative AI and custom assistants with the Claude API, like the one on this site.

Process automation

Flows that remove manual work and raise operational efficiency.
