"Chris rebuilt our entire transformation layer from scratch — clean SQL models, thorough testing, real documentation. Within two months our analysts stopped going to engineering for data questions. That's the standard he sets."

"We handed Chris a mess of Excel files and a spreadsheet-based P&L process. He came back with a proper data warehouse, a Tableau dashboard, and a model we could actually trust in board meetings. Night and day."

"What sets Chris apart is that he asks the right business questions before writing a single line of SQL. The dashboards he built for us were adopted immediately because they answered what we actually needed — not what we thought we wanted."

"Worked alongside Chris on a warehouse migration project. His data modeling instincts are sharp — he pushed back on our original star schema design with a better approach and was right. I learned a lot from working with him."

"Chris built our marketing attribution pipeline when three vendors had told us it couldn't be done cleanly in our stack. He documented every decision, wrote the tests, and handed it off in a way that our junior analyst could maintain. That's rare."
