About Me

I'm a Site Reliability Engineer with over a decade of experience supporting and scaling Linux and Windows-based infrastructure across on-premises, hybrid, and virtualized environments. I specialize in implementing infrastructure automation, observability solutions, and incident response procedures.

My expertise includes performance tuning, system monitoring, and reducing operational toil through scripting and configuration management. I'm passionate about SRE principles, automation, and building reliable, scalable systems that serve both internal teams and customers.
