Professional summary
Passionate system engineer with over 25 years of experience in new technologies. A true self-taught generalist, I combine solid expertise in systems administration (Windows/Linux) and development with a strong interest in cross-functional projects blending software and hardware (electronics, mechanics). My recent experience in IT production at a major bank has allowed me to master critical environments and CI/CD processes. Rigorous and curious, I am looking for a new senior role where my versatility and ability to turn ideas into reality will be valued.
