    En résumé

    Smart & creative, "making the web" fascinated me from very early on: my first website went live in the mid-1990s on GeoCities. I studied computer science in Germany while working for web agencies on different projects. Via Australia I moved to France to join Criteo as a web developer and also one of the first employees. Moving on to French Gmaps-competitor Mappy as a developer and then to Symfony-editor SensioLabs as a technical project manager. In January 2013 I joined the BlaBlaCar adventure as the first manager in the then small engineering team. Ever since I focus on building and scaling the development team by constantly adapting process and integrating new talent. The team grew from one single French five-person team to a dozen distributed and fully agile teams with 30+ people in only two years. In 2015 I successfully leveraged the inception of a second engineer hub in Warsaw, allowing us to scale faster and thus to respond to our ever-growing business. I am always looking for dynamic and skilled people to join the crew (in Paris or Warsaw), get in touch if you feel being the right person. What I'm good at: - improving processes by finding matching methodologies - engagement and teamwork - shaping and living tech culture - having a good technical judgement - interacting with both engineering and business teams - sharp oral and written communication in several languages
