Professional Experience

• Mastered troubleshooting methodologies spanning from kernel-level to user-facing application issues, becoming escalation point for complex production problems
• Designed and maintained multiple Kubernetes clusters on bare metal from initial deployment through long-term operations, handling cluster provisioning, storage integration, scalability planning, and production incident resolution without managed service dependencies
• Configured and managed Kubernetes networking including CNI plugin implementation, network policy enforcement, and debugging complex traffic flows across pod, service, and external network layers
• Performed hands-on datacenter operations including physical setup, configuration, and urgent remediation of network devices, ensuring minimal downtime during critical infrastructure incidents
• Worked extensively with Kubernetes operators and custom resources, deploying and troubleshooting controller-based applications and managing reconciliation loops for automated workload management
• Designed, deployed, and operated multiple Ceph distributed storage clusters for production workloads with CSI integration, tailoring architectures to client-specific requirements and resolving complex storage issues including data consistency challenges, cluster rebalancing, and critical recovery scenarios requiring deep understanding of RADOS internals
• Built comprehensive Ansible automation framework managing the complete infrastructure lifecycle from bare metal provisioning through application deployment, enabling consistent configuration management and safe infrastructure changes
• Implemented security practices across the infrastructure including RBAC configuration, IAM policies, secrets management with Vault, and security-focused alerting for anomaly detection
• Integrated and maintained diverse open-source technologies and workloads deployed on Kubernetes clusters, handling application lifecycle management, performance optimization, and ensuring operational stability across heterogeneous environments
• Implemented full observability stack with centralized logging, cluster-wide metrics collection, distributed tracing, and unified monitoring dashboards (Grafana, Loki, Tempo, Alloy) correlating signals across the platform
• Established incident management practices including proactive alerting systems and detailed post-mortem analysis with technical root cause findings and business impact assessment
• Contributed to event-driven architecture using NATS as an event bus for microservice communication
• Maintained active technology watch across Linux and cloud-native ecosystems, continuously evaluating and adopting emerging tools and practices to keep infrastructure aligned with current industry standards
• Developed understanding of Infrastructure as Code methodologies and tools including Terraform for declarative infrastructure management
• Mentored remote engineering teams and established infrastructure best practices organization-wide
