Summary

I am an IT specialist with over 8.5 years of experience supporting telecom systems and enterprise infrastructure. Throughout my career, I’ve provided reliable 24/7 support often during rotating shifts, weekends, and overnight hours - ensuring system stability and quick incident resolution. My expertise lies in Oracle BRM, where I’ve worked extensively on Linux platforms, developed automation scripts, and used tools like Splunk and Dynatrace to monitor and troubleshoot critical systems. I care deeply about keeping systems up and running smoothly, finding ways to make everyday tasks more efficient through automation, and making sure both teams and users have a hassle-free experience.
