I've been an official Member of the GNOME Foundation for the past 13 years. I was previously president of the GNOME Foundation, among other things.
With over 19 years of involvement in the Free Software community and open-source methodology, I have a particular affinity with this branch of the IT industry. My experience in the field, combined with my background in business, makes me one of the very few publicly available bona fide free/open-source marketing & business management consultants on the planet who can claim expertise in the field with a straight face. If you're looking for someone with a deep understanding of how the FLOSS community works, thinks and feels, and who can help your business integrate with it the proper way, you may be interested in my services.

Code & Project Management
For an overview of my code contributions to established projects, see the summary on OpenHub (or the full graph of code contributions over the years). You can also look at GNOME GitLab profile and my GitHub profile (you'll have to click through the various years of the graph).
Here is some software I wrote and/or managed:
- GNOME Calendar, the most beautiful calendaring app for Linux.
Since 2023, I am co-managing the project by handling product design, setting a new comprehensive and actionable roadmap, allocating developer resources, and effectively operating a turnaround for this software development project in the public interest. - Getting Things GNOME, the best Free & Open-Source personal productivity app to put the GTD methodology into practice.
Since 2019, I have taken over the management of this established software project in order to put it back on track for sustainable community-driven development. To that effect, I have restructured the project's direction for lean & agile production and overhauled the “Developer Experience” to facilitate the onboarding of new contributors. I also designed and wrote some of its code. Read case study - Pitivi, a video editing application for which I have been an official co-maintainer and interaction designer for 5+ years.

- Specto, notification software
- Post-install installer for Ubuntu, a software setup tool for freshly installed Ubuntu machines
- FrontBringer, a script to manage postponed files
- My semi-automated PHP lightbox gallery script
- Tango icon theme for Apache
- Recipe Manager
Quality assurance
My continued involvement in Free and Open Source software has made me file hundreds of bug reports and thousands of comments on various pieces of software that I have used and loved. Over time, I have involved myself in bug triaging to ease the developers' task. My bug reports are scattered over the web, but are for the most part contained in:
- GNOME (the majority of my work is over there; nominated among the top bug reporters in 2009 and in 2010)
- LibreOffice
- OpenOffice (obsolete)
- Abiword
- Ubuntu and others (Launchpad)
- Freedesktop
I also have a list of some of the top bugs I'm proud to have helped solve or investigate (due to limited time, I don't update that list that often, however).
I maintained Pitivi's automated user interface test suite for some years.
