About Jérôme

My job search is focused on projects in Typescript (but I am willing to learn other languages), for which development best practices are important (TDD, SOLID, clean architecture, DDD...).

To go back over my background:

After my engineering school (Arts et Métiers), I worked for two years in the oil industry on offshore platforms in Africa.

I retrained in web development by following the Wagon training in Paris (in Ruby on Rails). I then worked for ENGIE for 8 months as a Ruby on Rails developer.

At the beginning of 2018, I trained at Le Reacteur (10-week bootcamp) in Javascript technologies: JS, React JS & Native, NodeJS & Express, MongoDB.

I then followed several months of missions in React Redux and NodeJs, and particularly in Typescript. Notably at Axa, from February 2019 to August 2020, (in Typescript /React/Redux/nodeJS).

In recent years, I have become very interested in and trained in software design best practices (craftsmanship): TDD, SOLID code, hexagonal architecture (clean architecture)... And I had the chance to put all these principles into practice, first in personal projects, then as an entrepreneur of general interest for the Paris Fire Brigade from September 2020 to June 2021.

Since July 2021 (i.e. 4 years), I have been working for a beta.gouv state startup as Lead Dev.
