About Sébastien

Freelance Developer for over 7 years, I am curious, passionate, and I like a job well done.
I pay particular attention to bringing added value to my clients.

I am frequently looking for new challenges and I like working in a team!

I have fullstack experience (Vue.js, ReactJS, JavaScript, Node.js, Python, Flask, Django) as well as several tech lead experiences in small teams.

I REALLY enjoy working with business analysts to define business needs and I LOVE working in a team! :)
