Summary
For more than 8.5 years, I have worked as an IT professional who has supported telecom systems, enterprise infrastructure, and cloud-based terrains. I have offered continuous support, including during shift rotations, weekends, and nights to ensure timely system stability and incident resolution. My strengths include Oracle BRM and I have done considerable work on Linux OS, writing automation scripts, as well as on Azure Monitor, Splunk, and Dynatrace, which are used to monitor and proactively troubleshoot critical systems. I have also integrated Azure DevOps into deployment pipelines to aid CI/CD workflows. I strongly believe in the importance of system uptime, automation of repetitive tasks for improved productivity, and providing a seamless experience for both teams and end users.
