Freelancer profile translated to English.

Description

My career has allowed me to acquire many skills and has highlighted my great adaptability and professionalism.

With over 20 years of experience as a Linux System Engineer, I work as a freelancer to support companies in the design, deployment, and optimization of their technical infrastructures. My mission is to transform your challenges into robust and efficient solutions, based on a pragmatic approach and constant technological monitoring.

I specialize in complex Linux environments, with recognized expertise in distributed storage systems and high-performance computing (HPC/HTC) infrastructures. My goal is to provide you with strategic advice and operational support to ensure the scalability, reliability, and efficiency of your systems.

As evidenced by my personal achievements, I am comfortable developing Shell scripts (Bash or POSIX) traditionally or with modern tools such as AI code generation.
