About Basile

I develop web and mobile applications with React, React Native, and Node.js. What I bring in addition to code: a product vision, attention to detail, and engineering manager rigor. At Shine (neobank, 2020-2022), I managed a team of six developers while staying hands-on with the code. Before that, I was a developer at Capitaine Train (now Trainline).

I graduated from École Polytechnique and EPFL with a degree in computer science, after completing preparatory classes (MP) at Hoche.

My preferred technologies are TypeScript, React, React Native, Node.js, PostgreSQL, and CSS. I also use AI tools in my daily workflow (Claude Code in particular), which allows me to deliver faster while maintaining clean and controlled code. It is precisely because I have 10 years of experience that I can effectively leverage these tools and guarantee the quality of the result. I can also work entirely without them.

I am available approximately 10 days per month, either consecutively over 2 weeks or spread out two days per week. I work from Berlin, remotely or at your premises if you are in Berlin. I can also easily come to Paris or its surroundings.
