Data Analyst who builds the dashboards nobody has to explain twice.

Methodology

Strip the noise

SQL · Statistical reasoning · BigQuery

Remove vanity deltas. Use SQL and statistical reasoning to answer why a metric moved, not just that it did.

Translate to decisions

Power BI · Streamlit

Build what does not exist

Full stack · Shipped

When the tool does not exist, build it end to end. Stop the leak at the source.
