About Arthur

Full-stack developer for over seven years, after having touched on many things (Front-end, Back-end, Infra, Product Management) in startups of various sizes, I decided to venture into the world of freelancing.

I am open to all types of missions, my preference going to what I am particularly fond of: projects that are both front-end and back-end – if possible on technologies I know well: React, Python, React Native, Node, etc. – and with a strong ambition and product dimension.

During my past experiences, I have always had a particular fondness for Product Management and the interfaces between PM and Dev: Agile methodologies, planning, prioritization, and it is with pleasure that I will provide my expertise on these subjects during the mission.
