Back to original languageAbout Jean-Paul
Computer engineer, architect and full-stack developer for over 15 years, I have worked for large groups as well as for startups (Aircall, Accenture, Gaz de France, PSA, BNP Paribas etc.).
My field of expertise includes: architecture, fullstack development, implementation and management of infrastructures (servers, cloud), project management and team management.

I mainly work remotely on short missions (<= 3 months) renewable.
I favor iterative cycles (agile methods), on digital projects with high stakes (strong technical or architectural constraints, algorithmics, proof of concept, tight deadlines).
