01 / Selected projects

Selected work.

Professional mobile work, a product I built and maintain, and an open-source app with offline workflows.

Team contribution

Trait

Mobile calls & workspaces

Calls that need to work beyond the chat screen.

I connected React Native call screens to realtime media and server state, and added workspace loading and recovery flows.

My work on calls, workspace startup, and mini-app hosting was merged into the team’s codebase.

02 / Independent product

Cutroom.

From a long recording to clips worth sharing.

I built an AI-assisted editor that finds highlights, lets creators refine captions and framing, and exports videos for social platforms.

I built the editor, background processing, accounts, and prepaid-credit workflow, and continue to maintain the product.

03 / Open-source project

Fieldwork.

Complete inspections without a signal.

I built a React dispatch desk and an Expo app that lets field workers save checklists and photos offline and sync their reports when they reconnect.

The web and Expo apps share a TypeScript sync engine. Stable submission IDs keep a retry from creating a duplicate report.

02 / Background

Recent experience.

I’ve worked in frontend development since 2020.
