About Matheo

I have been a DevOps developer in apprenticeship at Harmonie Mutuelle since 2022, currently pursuing an MAALSI engineering degree at CESI. I am new to freelancing, but I already have over 3 years of real experience in companies on concrete projects: Java / Spring Boot, Angular, PostgreSQL, CI/CD (Jenkins, GitHub Actions), Docker, automation, and industrialization.

My goal in freelancing is simple: to provide serious, clean, and structured work, while continuing to progress and help companies move faster in their projects. I am young, motivated, responsive, and particularly attentive to details. Every mission is an opportunity for me to prove my worth.

I work on:

Back-end development (Java / Spring)

Front-end development (Angular / TypeScript)

CI/CD, pipelines, automation

Docker, DevOps environments

Software quality, testing, integration

I am mainly looking for short or targeted missions: bug fixes, feature additions, DevOps industrialization, setting up automation, or optimizing existing systems.

If you are looking for someone reliable, involved, and truly committed to the success of the project, I am here to help you.
