Passionate about Open Source and technology with 12 years of experience, I offer my services to support you in your projects.
Initially, at an integrator, I built a solid experience in infrastructure, which allowed me to tackle a wide range of technologies in missions within various business sectors.
Having always worked on Linux/Unix systems, my appetite for Open Source has led me to this specialization.
For nearly 3 years, I was the technical referent for Linux/Unix systems and Open Source solutions within an international design office specializing in civil engineering. With a mixed build/run profile, I am capable of providing technical assistance, as well as working on specific projects for which I will commit to meeting deadlines.
