Platform and cloud engineering role in projects domains ‘IoT & Background Verification’
System Administration - Linux Administrator and Build Engineer: I was part of Linux/Unix Build Team, responsible for the maintenance and management of over 4500 Linux servers, encompassing both physical and virtual machines. With a commitment to providing 24/7 support and delivery to clients, I ensure that service level agreements (SLAs) are consistently met. My role involves proactive monitoring of server health, including file system, CPU, memory, and disk utilization, collaborating closely with application teams to maintain server stability. I have extensive experience in troubleshooting major incidents and issues, liaising with OS vendors to resolve them efficiently through the raising of PMR cases. Additionally, I handle LDAP configuration and provide authentication and Sudo access to users, along with coordinating with application teams for planned outages and implementing OS patches, BIOS, and firmware updates. Proficient in OS installation and configuration, particularly RHEL 5/6, I excel in tasks such as LVM creation, filesystem expansion, and performance monitoring using tools like TOP, VMSTAT, IOSTAT, and SAR. My expertise extends to network interface management, user and group administration, software and patch management using RPM and YUM, and automation with Cf-engine. I also have proficiency in virtualization, including VM creation, resource management, and change control presentation in CAB meetings, along with coordinating downtime and executing approved changes during weekends in collaboration with application teams
