CTO @ I helped start Fauna, a database startup. From March 2012 to Present (3 years 10 months) Technical Lead, Storage @ I was one of two technical leads of the team at Twitter responsible for the core storage services that backed the site, including Tweets, Follows, and Users. - Maintained and operated existing core services written in Scala. - Led the project to design and build a scalable storage service for user records, and helped coordinate a complex integration involving many existing legacy concerns and 3 different teams. - Helped streamline and hand off day-to-day operations of Twitter's sharded MySQL services to the DBA team. From February 2011 to March 2012 (1 year 2 months) Senior Software Engineer, Infrastructure @ I worked on a small, fast team that built and maintained many of Twitter's critical back-end components written in Scala and Ruby, at a period when the site was growing extremely rapidly. My responsibilities included the development and deployment of new systems, maintaining existing ones, and responding to availability issues with the live service. - Designed and built a scalable storage service for tweets, which when deployed resulted in a drastic increase in the availability of the system in the face of large spikes of incoming tweets. - Helped rebuild and increase the efficiency of Twitter's primary asynchronous processing pipeline, responsible for ensuring the delivery of hundreds of thousands of tweets per second. From January 2010 to January 2011 (1 year 1 month) Software Engineer @ I was a full-stack engineer on multiple social games for Facebook's platform built using Ruby on Rails that ended up being played by millions of people. I worked on both fast-paced prototype projects as well as longer term maintenance, and was responsible for the day-to-day health of the systems I worked on. - Devised and open sourced a method to perform zero-downtime schema changes in MySQL for very large tables. - Ported a large subset of jQuery to Facebook's FBML javascript sandbox. - Designed and built a reactive, server-driven javascript event framework that allowed for easily extensible, rich UIs to be built using modular, unobtrusive js components. - Built a low latency image compositing service that was was used to generate on-the-fly in game assets and user avatars. From May 2008 to January 2010 (1 year 9 months)
