Experienced Linux System Administrator specializing in server optimization.
What I'm looking for
I am a dedicated Linux System Administrator with extensive experience in managing high-traffic websites and optimizing server performance. My journey began in 2014, and since then, I have honed my skills in server deployments, automation solutions, and technical support. I pride myself on my ability to troubleshoot complex server environments and enhance user experience through effective system performance analysis.
Throughout my career, I have worked with various technologies including Git, Kubernetes, and Ansible, allowing me to automate server configurations and streamline processes. My role at Touch Support, Inc. as a Shift Lead involved not only technical duties but also management responsibilities, where I supervised teams and ensured high-quality service delivery to enterprise clients.
