About Théophile

System Administrator and Ruby on Rails developer, I have acquired an unfailing taste for a job well done and a sense of detail at Capitaine Train, a startup acquired by Trainline for 200 million euros, then at Qonto, as a Freelancer in the SRE team.

My expertise (Ruby on Rails, System Administration, Gitlab CI, etc.), matters to me and my colleagues as much as my human values: kindness, empathy, and continuous improvement of team organization. I am highly attentive to the values of your project: do not hesitate to present them to me.
