I help founders build a data foundation that doesn't fall apart when they scale

Book a session

I advise founders and early-stage teams on data strategy and architecture, helping you get the fundamentals right before they become a scaling problem. Through fractional and advisory work, I help you decide what data actually matters for your business, then build it right the first time.

Build Review

Already have a system in place and want a second set of eyes? Share access or a walkthrough, and I'll review it live: what's solid, what's fragile, and what will break as you scale.

Walk me through what's slowing you down: duplicate data entry, tools that don't talk to each other, a process that only works because one person remembers all the steps. I'll ask sharp questions and give you a clear read on what to fix first and how.

Got a specific question? A tool decision you're stuck on, a workflow that's almost working, a "should I use X or Y" call you need to make? Send it over and I'll answer on my own time, usually within a day.
