Performance on Paper
Engineering Lead on Origami Studio

iOS apps, including original Starbucks app

I led an effort to build a visual programming environment for UI designers that lets them express and iterate on gestural UI easily.

One of my favorite parts was teaching a class to every newly-hired designer at facebook. The issues they encountered drove the roadmap for bugfixes and ui updates.

I worked exclusively on UI performance, maintaining a constant 60fps so gestures would feel smooth and not glitch

Paper would drop frames on certain facebook stories where the UI used lots of subviews, so I built tools to correlate layout timing with a video timeline. I also maintained our asynchronous UI framework, now called Texture (texturegroup.org)

Tried to play go with monte-carlo and neuroevolution techniques. Didn't work. 8 years later, with many orders of magnitude more compute and backprop, alphago succeeded
