Meta Quest Browser. You know, the Chromium-based web browser in your VR headset. That one.

Worked on novel cloud/device split-rendering of the Web, built atop the open source Chromium browser. Member of Amazon WorkLink from conception through launch.- Led a major change in client-side vector graphics rendering, from SVG to Skia CanvasKit (Web Assembly), delivering broad improvements to rendering correctness. Owned the research and prototype implementation. Brought the team up to speed on the project through formal knowledge transfer and ad hoc consultation. Decomposed task work enabling 3-to-4 engineers to work on the project in parallel. I am the single largest individual contributor (as measured by commit count) outside of Google to the open source CanvasKit project (at time of writing).- Drove the WorkLink Chromium Upstreamer Program which aims to submit non-sensitive code changes back to the open source Chromium projects. This program reduces maintenance burden, provides access to Chromium domain experts, and ensures the team stays informed of prevailing Chromium development practices. Shepherded 8 other engineers first upstream changes, and advocated for Chromium upstreaming/increased upstream collaboration across the Silk organisation. I was one of the Silk organisation's most active individual upstream contributors (top ~1–2%). - All the other things that come with an engineering leadership role at Amazon: acting as a technical consultant to engineering and management, mentoring more junior engineers, interviewing 50+ engineering candidates, instilling engineering standards, etc.

Worked on novel cloud/device split-rendering of the Web, built atop the open source Chromium browser. Split-rendering was applied to multiple initiatives, including rendering pages for the Amazon Silk web browser on Kindle tablet devices, and Amazon WorkLink. Member of Amazon WorkLink from conception through launch.- Core contributor to proprietary cloud rendering technology built atop Chromium.- Conceived and implemented a novel client-server font matching approach enabling text to be rendered correctly in any web browser, not just Silk on Amazon Fire tablets. This contributed to enabling cloud rendering applications like WorkLink to exist outside of the Amazon Fire tablet ecosystem. In the process, eliminated the need to partition cloud rendering containers by OS, simplifying server-side infrastructure.- Drove team-wide operations including ownership of a weekly ops review for a group of ~30 engineering and management stakeholders.- Drove improvements in metrics gathering and instrumentation, performance profiling, monitoring, and alarming. Worked with multiple other teams throughout Amazon on integrating with their telemetry solutions, ported Chrome's CPU profiler to work with headless Chromium, wrote a suite of scripts to gather and plot performance data, and set standards around metrics and alarming.- Circa 2016–2017: worked on cloud-accelerated page loads for Kindle Fire tablet devices.

April 2016–April 2017: worked on novel cloud/device split-rendering of the Web, built atop the open source Chromium browser. Split-rendering was applied to multiple initiatives, including rendering pages for the Amazon Silk web browser on Kindle tablet devices. March 2015–March 2016: member of the Amazon API Gateway launch team (new AWS service). Helped scale/maintain/operate the service. Built a concurrent on-box metric batching/aggregation system which contributed to scaling the service to handle two orders of magnitude more requests/sec.

Worked from founder's garage before moving to a real office. Contributed to Google App Engine web backend and Objective-C iOS app for the "startup" (now unicorn) which make the iAuditor mobile app.

Tutored students in procedural and object-oriented Python and Java.

Made design and implementation contributions to the control plane of a distributed data storage and retrieval system with built-in software failover (pre-cloud era) . Wrote serial communication software targeting Windows Mobile phones and PDAs (before the iPhone was a thing). Made design and implementation contributions to Windows native dashboard applications (before everyone moved to the Web). Wrote customer-facing web reports tablulating equipment monitoring data.Technologies: C#, Microsoft .NET Framework, Windows Communication Foundation (WCF), SQL Server 2005 (full and compact editions), ASP.NET MVC, ASP.NET Web Forms, NHibernate ORM, Rhino Mocks, Dundas Gauge and Dundas Chart (3rd party .NET gauging and charting packages).
