Aniket Arora

DevOps & OpenShift Engineer, 5 years, driven by building resilient infrastructure that never goes down on my watch.

Built

OpenShift clusters from bare metal to production across AWS, Azure, ROSA, and ARO. Automated cluster upgrades (OCP 4.12→4.20) and day-2 operations with Bash and GitOps (ArgoCD), cutting manual toil. Hardened platforms end-to-end — networking (HAProxy, MetalLB), storage (ODF), security (Qualys, QRadar, CrowdStrike). Resolved 100+ production incidents via ITSM without a single missed SLA.

• Built and configured OpenShift clusters from scratch on VMware ESXi and bare-metal infrastructure, implementing custom cluster architectures for enterprise environments.
• Designed and deployed HAProxy and Keepalived for High Availability (HA), cluster ingress, and external load balancing, along with MetalLB for bare-metal LoadBalancer services.
• Installed, configured, and managed core OpenShift platform components, including OpenShift Data Foundation (ODF), Monitoring, Logging, Single Sign-On (SSO), Quay Registry, Enterprise Storage, Grafana, Argo CD, and HTPasswd Identity Provider.
• Planned and executed OpenShift cluster upgrades from v4.18 to v4.20, ensuring minimal downtime through pre-upgrade validation, post-upgrade verification, and advanced troubleshooting.
• Designed and implemented Centralized Argo CD (GitOps) for automated application deployment, configuration management, and version-controlled releases across multiple clusters.
• Onboarded and managed clusters using Red Hat Advanced Cluster Management (RHACM) for centralized multi-cluster lifecycle management, policy enforcement, and governance.
• Implemented Governance Policies using RHACM to ensure cluster compliance, configuration consistency, and enterprise security standards across Production and UAT environments.
• Automated etcd backups using CronJobs and configured Veritas NetBackup for enterprise application backups, ensuring data protection, backup reliability, and disaster recovery readiness.
• Configured and maintained OpenShift Logging, Log Forwarding, and centralized log management to improve troubleshooting, auditability, and operational visibility.
• Built and managed monitoring dashboards, Prometheus, Grafana, and alerting solutions to improve platform observability, proactive monitoring, and incident response.
• Integrated enterprise security solutions, including CrowdStrike and Qualys, to strengthen endpoint security, vulnerability management, and platform compliance.
• Managed physical server infrastructure using iDRAC and ExClarity, including BIOS tuning, firmware validation, and hardware configuration for optimal platform performance.
