Some of my work

In recent years I've worked with some amazing startups such as Opbeat in Copenhagen, Pexeso in San Francisco, or Jack in Prague. Previously I was co-founder and CTO of a Copenhagen-based startup. I've also created a bunch of open source projects:


CLI HTTP client, user-friendly cURL replacement. The most popular Python project on GitHub.


Music player for Dropbox and YouTube built with JavaScript, Backbone.js, Sass/Compass, Python, Tornado, Redis, MongoDB.


Bitcoin trading bot with a real-time dashboard implemented in Python, Tornado, CoffeeScript/JavaScript, Backbone.js.


JavaScript support for recurrence rules for calendar dates as defined in the iCalendar RFC.


Python client for Last.fm which also provies a non-blocking client for Tornado.
