From 2001-2013, I was the lead front-end engineer for a conferencing and collaboration platform. In addition, I designed APIs, wrote and maintained API documentation, and served as UI designer.

In 2000-2001, I was the front-end engineer for a product that built 3D models of the user's head from photographs, and animated those models based on the user's movements. The UI was built entirely in OpenGL.

I have limited experience with animation libraries, but I pride myself on being able to pick up new technologies and paradigms the first day on the job. To demonstrate this, I taught myself the Motion animation library, and built four demos over the course of a day or so. (November 2025)

Code

In the 2010s, I designed this website for personal use, as a template on top of the DokuWiki system. It features:

• Responsive, mobile-friendly design. There are three breakpoints when resizing the window horizontally, to support modern wide screens, narrower screens, and mobile devices.
• Customization: The title, background image and sidebars can be customized for each site and page, and configuration optionally cascades to child pages.
• Performance: I made a number of performance improvements to the core DokuWiki system, following best practices like compacting icons into a single file, minimizing HTML, CSS and JavaScript code size, and building the popular fastwiki plugin to improve core performance.
• Customized tooltips: I created the open-source autotooltip plugin to provide summaries of links and improve the tooltip experience. Sample tooltipplugin-autotooltip__default plugin-autotooltip_bigThis is a tooltip
