Administered and supported Linux servers (RHEL, CentOS, Ubuntu) — installation, configuration, patching, upgrades, and day-to-day troubleshooting to maintain production stability.
Automated recurring tasks with Bash scripts, reducing manual effort and lowering incident recurrence by 30%.
Tuned system performance (kernel parameters, storage, I/O) and monitored resources using top, vmstat, iostat, and centralized logging for proactive issue detection.
Managed user accounts, groups, file permissions (SUID/SGID, sticky bit), and security hardening to meet compliance and reduce unauthorized-access risk.
Configured and troubleshot network services (DNS, NFS, SSH, firewalld, VPNs) and used tcpdump/ss/ip for root-cause network investigations.
Hands-on AWS experience: EC2 (custom AMIs, autoscaling, EBS), S3 (lifecycle, versioning, encryption), IAM (roles/policies/federation), CloudWatch – configured alarms, dashboards, and log monitoring, enabling faster issue detection and reducing MTTR by 25%, and VPC networking.
Implemented image-building and deployment automation (Image Builder, custom AMIs), accelerating provisioning timelines by 40% and improving consistency across environments.
Owned incident management and on-call rotations, performing RCA and remediation to minimize service disruption and meet SLA targets.
Collaborated with cross-functional teams and vendors to resolve storage, OS, and cloud-integration issues; documented runbooks and playbooks for repeatable operations.
Strong focus on observability, cost-aware resource optimization, and DevOps-friendly practices to support fast, reliable delivery of infrastructure.
