Radio Garden made radio feel like geography. Atlas FM pushes that feeling into a native product philosophy, with the iOS App Store rejection now part of the story and a macOS version already in progress.
Continue readingDesign system infrastructure for GitHub Mobile, built with an agent-first workflow. Shared tokens, SwiftUI and UIKit parity, a demo app, and a Figma plugin that reads the same source as the code.
Continue readingA shipped cross-platform workflow for tracking Copilot agent sessions, reading native logs, and taking the next step on mobile. My part lived in the production stretch, in implementation review, cross-platform coherence, and the edge cases that make the feature trustworthy.

I use AI to synthesize source material, push back on weak directions, and move into SwiftUI prototypes that actually run. Faster mockups isn't the goal, it's getting to something real enough to judge on device.

Most note apps try to be everything. I built Kurzgedacht with stronger opinions around temporary focus, clean attachments, forgiving search, and a data model that keeps those decisions honest.

Most color tools work, but few feel good. (Alles) Paletti is a SwiftUI experiment in animation, haptics, and the small details that make a utility feel considered.
Continue readingShutting down a beloved product is mostly a trust problem. We moved millions of users into Microsoft To Do by treating the migration as the product, not as an export flow.
Continue readingThe language we use in meetings shapes what we build. Call it "sharing," and you build access, but call it "collaboration," and the team starts looking at how people actually work together.

I built a stopwatch to see what happens when a simple tool has nowhere to hide. It forced decisions about precision, trust, and the imperfect conditions people actually use timers in.
Continue readingI pushed back on forking repositories on GitHub Mobile because I thought it was too heavy for mobile. Users proved me wrong, which changed how I read feature requests.
Continue readingNotifications are usually noise. We designed Focused Notifications to reduce the noise without breaking trust. Most of the work was respecting where users already were.
Continue readingCode review is heavy work. I worked with engineering to break it into smaller mobile steps without losing the context that makes reviews safe enough to trust.
Continue readingIC product design across native apps, product systems, AI workflows, design systems, and the parts of the work that only get honest once code is running. I do my best work where product judgment, systems, and code meet, and where teams care about quality all the way into production.
Most recent work: design system infrastructure for GitHub Mobile (Primer iOS, agent-first build, endorsed by leadership for production rollout), shipped Copilot agent sessions across iOS and Android, and a self-started iOS information architecture prototype on TestFlight. Earlier, I led the Wunderlist to Microsoft To Do migration at a 99.35% success rate.
