I worked primarily on the web document capture flow, as well as developing SDKs so that our customers could deeply integrate our IDV flow into their own web experiences. I also worked on adjacent build and infrastructure improvements to improve our internal dev experience, such as:- Setting up and supporting end-to-end testing of our web capture flow- Updating our customer dashboard site to use a standard component framework- Migrating our frontend containers and builds to ARM, allowing for a native dev experience on our Apple Silicon MacBooksBerbix was purchased by Socure in 2023, and I was part of the transition team.

I most recently worked on the Airbnb Lux team, on supply tooling. We worked with the Luxury Retreats operations team in Montreal to build tools to make it easy to schedule, inspect, and activate luxury listings around the world.Before that, I was on the Search team at Airbnb. That team owns large swaths of the guest flow, including the home page, the search page, and the listing pages. I was responsible for architecting and implementing the successful transition of the search page from Rails / Mustache to React.Prior to that, I was on the Core Web team at Airbnb, which was primarily responsible for building developer tools. In addition to leading the engineering efforts behind the massive website redesign that happened alongside the launch of our new company brand in 2013, I was also one of the primary authors and maintainers of O2 (née Oxygen), which was our HTML / CSS / component framework in the spirit of Bootstrap or Zurb Foundation. It has since been deprecated in favor of DLS, but I like to think that O2 had a hand in its genesis.Before my role on Core Web, I worked on a number of nifty things, both user-facing (e.g. internationalization tools, core flow pages, user tools) and on the architectural side (e.g. dynamically-processed user photos).

I wrote software that took advantage of NeuroSky's brainwave-sensing headset technology. This included various demonstration games and visualizations (in the Unity game engine), as well as desktop apps (in Mono/C#). I also wrote various APIs (TCP, Mono/C#, iOS) for the headset, to make it easier for developers to build software that takes advantage of the headset.On the side, I wrote a number of internal tools, such as a Wiki-markup-to-TeX converter to facilitate generation of documentation, and built the company's website and Shopify storefront with an in-house designer and a PM.It was an immensely creative and productive experience, and I learned a ton.

I started life as an FPGA designer, implementing algorithms in hardware that matched mass-spectrometry "fingerprints" with potential peptides (i.e. digested proteins).Eventually, I moved over to more user-facing work, building a web-based frontend for the analysis system. Done initially in PHP, and eventually in Rails.
