Projects
whoisedenfrost.com
Built with Next.js and a deliberately personal aesthetic. No UI kits — just custom fonts and CSS custom properties. The domain is whoisedenfrost.com — which is a question I actually went and answered.
Hypothesize
An AI-powered tool for turning raw product observations into developer-ready A/B test hypotheses and briefs. Audit pages, pull in analytics, annotate screenshots, and generate ranked, evidence-backed test ideas in minutes.
Coach Claude
An AI coaching layer on top of an open-source Apple Watch training backend. Claude reads real workout data via MCP — per-session notes, heart rate trend analysis, and training queue management built around your actual history.
Fields
A fork of Kevin Roose's read-it-later app, rebuilt around visual research. A lot of what's worth saving in UX and experimentation work isn't an article — it's a UI pattern, a campaign page, a screenshot. The original wasn't really built for that.
Screenshotter
A Mac menu bar app that takes full-page desktop and mobile screenshots of any URL in seconds. Python, Playwright, and Server-Sent Events — because opening DevTools for the fifth competitor in a row gets old.
The Book Club
A private web app I built for my own book club — because Goodreads is too public, a spreadsheet is too boring, and we deserved something with our name on it. Track reads, rate books, log meetings, and record what you ate, drank, and argued about.
