Led design and implementation for several foundational pieces of Figma's editor engine, used by hundreds of product engineers across all of our product lines.

Projects I led include:

• Our Wasm state-management/derived-data framework (think redux/recoil/jotai, but from scratch and in C++)

• Reimplementations of our design systems features (components, styles, variables, etc) to improve performance and correctness

• Our core internal debugging tool (think Chrome Devtools, but for Figma files)

Remix is a web-based platform used by city planners to design transportation systems. Customers include the New York MTA, London’s TFL, the city of Chicago, and the NTA of Ireland.

I managed five engineers and led the Collaboration product team, building features like permissions, sharing, and commenting.

I worked as the first and lead engineer on the greenfield New Mobility product, which helps city planners analyze and regulate scooters and bikeshare systems.

I worked on integer-programming problems for bus-schedule optimization, as well as frontend code to visualize the results, including a rewrite of much of the frontend in Typescript and Redux.
