Benjamin Van Ryseghem

I am a 36 years old software development enthusiast and I have the chance to live from my passion. I spent the last 10 years improving my skills, learning new things and working on awesome projects.

Margny-lès-Compiègne is a nice small town surrounded by a wonderful forest, and very close to Paris.

As I love living here, I will only consider remote positions.

Some highlights of FLOSS projects I developed or to which I was a core contributor
  • As the author of numbro I had the opportunity to collaborate with a great variety of people and to provide a formatting solution that it downloaded more than 13 million times a year, supporting more than 60 cultures. It is used mainly by companies and embedded in multiple frameworks as the default tool for currency formatting.
  • As a core maintainer of Pharo (an open source Smalltalk implementation), most of my Smalltalk projects have been integrated in the distribution. My other Smalltalk projects can be found on Smalltalkhub. Among those projects are the complete IDE solution, the main UI generation framework, a VCS solution, and a couple of widgets (tabs, circular menu, lists, etc.)
  • git-linter is a node-based command line tool and a docker-based GitHub/Gitlab CI integration that lint git commit messages using project-defined rules à la eslint. The code is distributed under the GPL 3.0 license.
  • SandGlass is an electron-based systray app used to track my working time. It provides a CLI for workflow integration and D3 based histograms of time per projects. The code is distributed under the GPL 3.0 license.
  • Great Things Done is a keyboard-centric GTD application based on Electron, and implemented in Clojure/ClojureScript. The front-end uses Reagent (an adaptor to React in CLJS), and implements some interesting features like a fully encrypted file-based database, global shortcut with macOS integrations, or Dock icon support. The code is distributed under the EPL 1.0 license.
  • ergotron is a hand-made custom keyboard I built from scratch. The firmware is based on the excellent ergodox-firmware by Ben Blazak. The firmware has been extended to support a lot more keys and LEDs, leading to a new hardware layout. The code is distributed under the MIT license.
A small glimpse at things I love to do during my spare time
  • Cooking is where I spend most time out of work. I love to prepare a nice meal for my friends and I. I am always improving my skills by experimenting new recipes and cuisines. The fact that it requires to be focused and precise is a great way to free your mind.
  • Bouldering is a very fun sport with an awesome community. Even though it is an individual sport, you are never alone, and people always offer hints and tips. It requires to always outperform yourself and be very focus which I find are providing great satisfaction.
  • Gaming is most probably the hobby I practise for the longest time. It is really enjoyable to dive in a completely new universe, with whole new set of rules to learn, and see how your past experiences can help you mastering this new challenge. This apply to video games but also to board games or role playing games. And beside being fun, playing has always be a great way to learn and experiment.
  • Miniatures painting is my new hobby, and probably the one I wanted to dive in for the longest time. I was always impressed by those showcases we can see in game shops, but never tried. When I got my 3d printer, I decided it was time to give it a try, and a couple of years later with 100+ mini painted I can definitely say I am hooked. It is quite magical to play boardgames with friends using only mini you spent hours painting.
My dream job
Great people to work with
We learn from our pairs and spend several hours a day with them. So having a good team spirit is mandatory. And a good team spirit comes from good team members.
Not just another brick in the wall
Everyone should matter and have the opportunity to impact on what they do. I am also strongly convinced that involved worker are more motivated and thus more productive.
I strongly believe in self-organized people as well as in self-organized teams. Decisions taken by doers are a lot more motivating and reflects better the team capabilities. Even though a team my need a leader occasionally, team members should be trusted to find the best way to reach the defined goals.
Remote positions allow to gather best suited people together. Not only the ones that happen to be located close by. Also mixing cultures brings creativity and opens minds.
