Open Source Engineer • DevSecOps • Reliability

Profile picture

Hi, I’m Nicolas, pleased to meet you! 🧙🏻

I automate things, hoping that one day everything will be! 🤖

I believe in continuous improvement and open collaboration, leveraging a transverse toolset of technical and relational skills, and have been working in international contexts for over 10 years. I’m skilled at breaking down complex systems/concepts and then synthesizing/articulating them. I think responsibilities and to some extent leadership should be owned and shared by everybody within the team.

To me, the best team is made of autonomous contributors who lean on each other: strong alone, stronger together 🤝
