About me.

I'm a Software engineer, passionate about Lisp, Smalltalk and the Web. I split my time between Stockholm (Sweden) and Brest (France). Oh, and I also spend most of my days in Emacs.


I'm an engineer in the dev team at Företagsplatsen. I previously worked in the RMoD team at Inria. I'm also the co-founder of Objectfusion, a company dedicated into building custom web applications.


  • I'm the creator of Amber, a Smalltalk that runs inside the web browser
  • I'm also the author of SmalltalkHub, a code repository and project management application for Smalltalk
  • I work on/maintain several Emacs packages, including js2-refactor, seq.el, map.el (in Emacs 25.1), stream.el, amd-mode, zerodark, niflheim, as well as some others
  • I'm working with Ben on Teamwall, an online tool made to help remote team members feel closer to each other
  • I contribute to MongoTalk, the Pharo driver for MongoDB, and Phriak, the Pharo driver for Riak.
  • I'm working with Esteban on Tide, a new web framework for Pharo and Amber.
  • I often hack my Emacs settings.

You can learn more about Amber on the GitHub page, and can find more projects on my Github and SmalltalkHub accounts.

Some presentations I gave.
