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 was also the co-founder of Objectfusion, a company dedicated into building custom web applications.


  • Since Emacs 24.5, I'm taking care of the releases of Emacs, and I work on/maintain several Emacs packages, including jade, js2-refactor, seq.el, map.el (in Emacs 25.1), thunk.el (in Emacs 25.1 as well), stream.el, amd-mode, xref-js2, zerodark, niflheim, as well as some others
  • I like to design websites & logos
  • I'm the author of objectjs, a Smalltalk-inspired object model for JavaScript, maintained together with Ben.
  • I'm working with Ben on Teamwall, an online tool made to help remote team members feel closer to each other (project currently on hold)

Past project.

  • I'm the creator of Amber, a Smalltalk that runs inside the web browser (I don't maintain it anymore)
  • I'm also the author of SmalltalkHub, a code repository and project management application for Smalltalk (I don't maintain it anymore)
  • I contributed to MongoTalk, the Pharo driver for MongoDB, and Phriak, the Pharo driver for Riak.
  • I worked with Esteban on Tide, a new web framework for Pharo and Amber.

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.
