Aside from commercial work I happen to contribute to open source a little. Samples of my non-commercial work can be found below:

Sql Reporter

A tool for generating reports on reduction of SQL performance in Rails app. It works alongside sql_tracker for diagnosing the queries generared by the Rails app


An Excel add-in for parsing numbers into human readable words in more than 6 languages. It is based on humango - a Go library facilitating the same functionality of which I am the author.


A simple tool for creating and editing sets of decks for Anki spaced repetition systems

More to come soon…
