I am a product-minded software engineer with specialization in interactive, complex, and highly-stateful user interfaces. I prefer to work with high-performing cross-functional product teams that make decisions using data and experimentation. I have a record of driving change via advocacy and education around software quality through a disciplined approach to unit testing and test-driven continuous refactoring. I have experience with adaptive bitrate video playback and the use of browser APIs to build performant multimedia experiences on both desktop and low-power OTT devices. I've been called a super-communicator, and I am an experienced speaker and educator.

I currently work at Airbnb. I used to work on the video player at Tubi. I spent two years before that working on 🎥a browser-based multitrack video editor. 🔷Find me on LinkedIn

Much of my recent and most interesting output is closed-source, but here are some assorted projects which I can share:

• modeload is a small, partly-vibecoded CLI tool to back-up and restore Cursor IDE custom agent mode configs-- a stopgap until Cursor supports this feature natively built to help my team share config (typescript, Cursor IDE; on NPM here)

• callback-batcher is a small library for isomorphic rate-limiting of events; won 2nd place at tubitv.com 2023 company hackathon (typescript, vitest; on NPM [here](https://www.npmjs.com/package/callback-batcher
• gcull is a small, well-tested CLI tool for interactively deleting merged and stale local git branches (typescript, vitest; on NPM here)
• gchk is a small, well-tested CLI tool for interactively checking out git branches (typescript, vitest; on NPM here)
• prettier-inittier is a one-line command that installs and configures Prettier in a repository (node, vitest; on NPM here)

• krnsk0.dev is my infrequently-updated dev blog (astro, deployed here)
• planetfall is a browser game with a complex data model built to explore some possibilities and constraints around mobx and mobx-keystone (deployed here)

• guser is a small, well-tested CLI tool for git user switching (Node, shelljs; on NPM here)
• ng-draw is a canvas-based shape-drawing toy built to learn HTML canvas and Angular (deployed here)

• sort_buddy visualizes sorting algorithms commonly taught in intro algorithms courses (react/redux; deployed here)
• snek_io is a multiplayer websocket game built for a hackathon (no client framework, express and socket.io backend; deployed here)
• pixalive is a multiplayer editor for animated pixel art built by a small team for a hackathon (react, HTML5 canvas, node, postgres; deployed here; desktop only!)
