Part-time on-call Data Center Remote Hands.

Performing server and network equipment installation, hardware replacement, cabling, troubleshooting, diagnostics, and basic infrastructure support for data center operations.

- Designed and deployed Kubernetes infrastructure (k3s, Cilium), focusing on networking, service exposure, and cluster reliability.

- Built and maintained a production monitoring stack (Grafana, Vector, VictoriaMetrics, VictoriaLogs) via custom Helm charts, improving observability and deployment consistency.

- Led migration from Docker Compose to Kubernetes, ensuring persistence, scalability, and service continuity.

- Implemented distributed storage (Vitastor) with pool configuration, volume provisioning, and Stateful workloads integration.

- Configured and debugged Kubernetes networking (Cilium IPAM, LoadBalancers, routing, external access).

- Diagnosed and resolved cross-layer issues across networking, storage, and orchestration (connectivity, volume mounts, service exposure).

- Hands-on with physical infrastructure: disks, RAID, NVMe, PCIe bifurcation; troubleshooting hardware-level issues and performance bottlenecks.

- Performed physical server migrations (1:1, block-level) ensured data integrity.

- Worked with VMware ESXi and Proxmox; administered Linux systems (Ubuntu, Debian, CentOS).

- Worked with datacenter networking (Cisco Nexus, Arista), troubleshooting L2/L3 issues including MAC spoofing and network instability.

- Used low-level tools (tcpdump, routing tables, ARP) to analyze and resolve network anomalies.

- Optimized rack-level resource usage (power, hardware allocation) in datacenter environments.

- Mentored a datacenter technician, improving operational processes and troubleshooting efficiency.

- Led infrastructure changes: cluster migration to new location without downtime and cluster redeployments.

- Deployed internal services (e.g., kube-vip, copycat) and integrated external metrics (VyOS, FastNetMon, IPMI) via collectd + Graphite.

- Worked with distributed components (etcd, storage backends).

- Bridged infrastructure and business needs, identifying issues early and improving system reliability.

VetCRM is a veterinary clinic management system that has been evolving for over 20 years. The platform is built on Java(Spring), Angular, and MongoDB and provides SaaS-based solutions for veterinary clinics.

• Automated infrastructure provisioning using Terraform, managing AWS EC2 instances, securitygroups, VPCs, and IAM roles.
• Developed and maintained Docker-based environments for development and testing.
• Configured Ansible playbooks for automated server setup and Docker container orchestration.
  Integrated SonarQube for automated code quality analysis.
• Managed AWS S3 storage for artifact retention and backups, implementing automated log rotation and cleanup scripts.
• Implemented Jenkins agents auto-scaling in AWS.
• Wrote Bash scripts to clean up old Jenkins builds and logs, saving 50% of disk space on the server.
