About

I enjoy solving complex Linux and hosting challenges, optimizing server performance, automating repetitive tasks, and improving operational efficiency. Over the past 6+ years, I've supported production environments running cPanel, DirectAdmin, Webuzo, Apache, Nginx, MySQL, DNS, and mail — handling migrations, security incidents, performance issues, and the day-to-day work that keeps services healthy.

My current focus is infrastructure automation with Golang and Bash — building CLI tools and backend services that simplify how hosting infrastructure gets managed and monitored.
