Building GitHub Code Search.

San Francisco, Ca, Us

I work on search and code search at GitHub. Some major projects I've shipped during my tenure:- New code search. I primarily developed document ingest using Go, but also contributed to the React frontend and Rust backend.- Extracted code search from GitHub monolith into a Go-based service, with large cost savings over prior solution.- Prototype search platform written in Go using Kafka compacted topics, sharded Elasticsearch indexes, and schema evolution. This was used to quickly ship an experimental code search prototype.- Implemented backend and frontend search instrumentation to measure query performance and usage.- Upgraded Elasticsearch from 2.4 to 5.6 in the monolithic github.com application.

Premise provides a platform that enables human-powered data collection in the physical world. I built backend systems in Scala, Java, and Python running on Google Cloud Platform. In addition to building new features, I focused on improving performance and optimizing developer productivity.

As the first non-founder engineer at Swiftype, I wore multiple hats, working on everything from backend systems to JavaScript libraries to writing documentation. I worked closely with the operations team to ensure service reliability with appropriate metrics, monitoring, and alerting.Some keystone projects I worked on include reimplementing Elasticsearch index management and query generation code, developing the initial version of the billing system, and document storage infrastructure.

I created the MinneDemo event (with Dan Grigsby) in 2006 and then started helping organize MinneBar. Today, minne✱ hosts events such as MinneBar and MinneDemo that attract thousands of people a year. It is one of the cornerstones of the Minnesota technology community.

I started Fundamental Constant to build applications for clients ranging from tiny startups to Fortune 500 companies, primarily using Ruby on Rails and Google App Engine, with a bit of iOS.

I co-founded this Y Combinator-backed startup as the sole technical founder. I built Scoreboard Photo Sharing, which allowed fans to see themselves on the jumbotron during games. It was used by teams including the Minnesota Twins, Chicago Fire, and the Saskatchewan Roughriders. During the YC program, I built ChatterBox, a Twitter and Facebook-based chat widget. It was used by sites like Timberwolves.com and Philly.com.We were part of the Summer 2009 batch of Y Combinator companies.

I built the majority of tumblon.com, a web app for parents with young children. Features included a developmental milestone tracker, blog, photo and video uploads, and database of developmentally appropriate toys and books. I implemented usability tests based on Steve Krug's methodology, which helped us clarify what we should be building.

Ruby on Rails developer for Slantwise Design, a web applications consultancy and product development shop. I was responsible for all aspects of projects from client relations and project management to technical leadership and software engineering, working with teams ranging from myself to five people.

I continued to work on the Ancept Media Server product (a web-based enterprise Digital Asset Management system) and advanced to Senior Software Developer.I developed several key features for the AMS 3.6-3.8 releases, including Lucene full-text search, workflows, adding support for Oracle in addition to DB2, and a REST API. I also streamlined the build process by automating it with a Python script.(In 2003, Stellent acquired Ancept. Then in 2006, North American Systems acquired Ancept Media Server from Stellent.)

Working on a small team, I built features for Ancept Media Server, a web-based Digital Asset Management system built using Java, DB2, and IBM Content Manager. I was responsible for major portions of asset model and persistence rewrite for Content Manager 8. I implemented content ingest "hot folders", reporting system, and screens for the Java Swing administration application. I also wrote migration program in Python to move data from a proprietary bug tracker to Bugzilla with zero data loss, then administered the Bugzilla system.
