## About

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.

## Sessions I offer

- [Build Review](https://www.everyexpert.com/ericcallahan/book/build-review) — 1 hour, $350.00
  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.
- [Systems Audit Call](https://www.everyexpert.com/ericcallahan/book/systems-audit-call) — 30 min, $200.00
  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.
