I’m co-founder of AppSignal, the leading European APM that provides insights into errors, performance issues, host metrics and custom metrics for Ruby and Elixir applications.
In 2005 I co-founded 80beans (Amsterdam), one of the first Ruby consultancies in Europe. In 2013 we shut down 80beans after transitioning to working on AppSignal fulltime.
In 1996 I wrote my first front-end code. In 2007 I learned about Sass (the CSS preprocessor) and haven’t written any CSS since. My specialties are maintainable HTML and CSS/Sass. Nowadays I only dabble in code for fun.
Speaking & teaching
The best way to learn is by teaching. I have presented at many events all over the world, including notable ones such as Smashing Conference, RailsConf (thrice), SassConf (twice), Madison Ruby, Rocky Mountain Ruby, CSS Day, Feature of Web Apps and CSS Summit. With topics ranging from front-end architecture and advanced Sass to neuromarketing for the web, I’m a Jack of all trades.
