Senior Software Engineer in New York, NY. By day I build the cloud infrastructure behind silicon manufacturing and chip test at Microsoft. On my own time I make Sill, a free, open-source app that puts any window from your Mac on your iPhone or iPad.

Any window from your Mac, live on your iPhone or iPad. Touch, Apple Pencil, trackpad and keys. No servers, no accounts, Apache 2.0.

• Swift on macOS and iOS: ScreenCaptureKit capture, hardware HEVC encoding, TLS-paired local and remote transport, iPhone Duo layouts.
• Launched as the #1 Mac Streaming app on the App Store (5.0 stars), #2 on Hacker News, with a 672K-view launch video and 25K+ iOS users and 25K+ Mac downloads in the first two weeks.
• Community contributors have submitted Android, Windows, Linux and visionOS clients. Every pull request runs CI and mutation-tested checks; releases are tag-triggered, with TestFlight and App Store uploads from the command line.
• Built end to end with Claude Code: custom skills, workflows, MCP servers and artifacts for development, marketing, video and design. AI for iteration and prototyping, every architecture and product decision my own.
