About Xavier

I have a background focused on networks and systems and I enjoy technical challenges and hardware. I currently hold a research position in this field and can allocate 25-28 hours of my time to freelance tasks in parallel (35 hours possible but not regularly).

Outside of that, I do a lot of programming and regularly practice with algorithm exercises. I am proficient in Python, C++, and Java, and I also believe I can optimize code. I can also use web languages like JavaScript and PHP, which I use for small personal projects, as well as SQL and Docker.

Among the most interesting projects I have completed are HTTP gateways for transitioning from the IP protocol to the NDN protocol, the beginning of a microservices architecture (all functional services and a simple orchestrator), and a backend for AI quality assurance tests.
