About Sébastien

I have a CIO role as well as a hands-on CTO role (with a significant product UI and UX dimension).
I can manage a product from A to Z in all aspects, with several successful and sustainable experiences thanks to the development best practices I implement.

I can undertake various types of missions:

- IT Development (NodeJS Typescript backend (REST/GraphQL), React frontend (Web/Mobile))
- Corporate IT Strategy (Group, SME, VSE, Startup)
- Team Leadership, CIO Management
- IT Budget Management and Optimization
- Technical Consulting (design, architecture, implementation, testing, CI, CD, industrialization, etc..)
- Recruitment (candidate qualification)
- Technical Audit (code review, architecture review)

Permanently perfectionist, therefore meticulous about details and well-done work.
