WireView
2025–Present

Mastodon for Android
2022–2025
Took our learnings from the iOS app and adapted Mastodon to the Material Design cinematic universe. I designed some novel safety and privacy features, bespoke profile cards, and some really nice easter eggs. It’s one of the best Android apps available.

Mastodon for iOS
2021–2025
Led design for Mastodon’s official iOS client. We focused on clear visuals, safety features to prevent harassment, and getting people onboarded and familiar with the platform. Created a native app experience aligned with Mastodon’s decentralized and privacy-focused ethos.
Buildwatch
2020
I designed Buildwatch, a native macOS app born from internal frustration with slow Xcode builds. It gives devs aggregate analytics of their build times, spot bottlenecks, and finally figure out why the hell their SwiftUI previews are crawling.
