What I'm looking for

I am seeking a challenging role in a collaborative environment that fosters growth and innovation.

With over 7 years of experience in IT infrastructure management, I am a dedicated Systems Administrator skilled in both Windows and Linux server administration. My journey began with a Master's degree in Network Administration, and I have since honed my expertise in customer service and technical support. Currently, I am expanding my skill set through a DevOps training program, focusing on automation tools such as Docker, Kubernetes, and Terraform.

Throughout my career, I have successfully contributed to improving customer satisfaction by diagnosing critical line issues and coordinating technical interventions. My proactive approach has allowed me to identify and resolve potential problems before they impact users, ensuring high service availability. I thrive in dynamic environments where I can leverage my creativity and rigor to support teams effectively.
