Pushkar Kumbhare

DevOps and Cloud Infrastructure Engineer with 4 years at Tata Consultancy Services (TCS), Pune — delivering production-grade infrastructure across AWS, Kubernetes (EKS), Jenkins CI/CD, Terraform IaC, and Docker in enterprise environments. Brings a unique advantage of hands-on data center and on-premise infrastructure depth alongside cloud-native DevOps engineering, enabling end-to-end ownership from physical hardware to cloud-native deployments. Maintained 99.9% uptime across 100+ Linux production servers, reduced MTTR by 18% via structured CloudWatch observability, led on-premise-to-AWS migration end-to-end, and upheld SLO/SLI compliance through incident postmortem documentation and ITIL-aligned RCA practices.

DevOps & Cloud Infrastructure Engineer at Tata Consultancy Services (TCS) (2022-05 – Present)

• Administer 100+ Linux (RHEL/Ubuntu) servers across production and staging environments, sustaining 99.9% uptime through proactive monitoring, patch management, and structured incident response.
• Architect and maintain AWS cloud infrastructure (EC2, VPC, IAM, S3, RDS, Route 53, ALB, Auto Scaling, EKS) supporting multi-tier, high-availability enterprise workloads across production environments.
• Engineer end-to-end CI/CD pipelines in Jenkins integrating Git, Docker, and Kubernetes (EKS) — eliminating manual build and deploy steps, enabling faster and consistent releases across multiple environments.
• Provision repeatable, version-controlled AWS environments using Terraform IaC (VPC, EC2, IAM, Security Groups), eliminating manual provisioning errors and infrastructure drift across dev, staging, and production.
• Orchestrate containerized workloads on Kubernetes (EKS) — managing Deployments, Services, HPA, ConfigMaps, and rolling updates in production, achieving zero downtime during application releases.
• Reduced Mean Time to Resolution (MTTR) by 18% by implementing structured CloudWatch dashboards, metric alarms, and log-based alerting, improving infrastructure observability and issue detection speed.
• Automate repetitive Linux administration tasks — user management, log rotation, disk monitoring, and server health checks — via Bash scripting, reclaiming ~4 hours/week of manual operational effort per engineer.
• Lead on-premise-to-AWS workload migration end-to-end: capacity planning, VPC design, network configuration validation, cutover coordination, and post-migration smoke testing with zero data loss.
• Manage P1/P2 incidents via ServiceNow ITSM aligned with ITIL practices — providing on-call support, maintaining SLA/SLO compliance, and producing incident postmortem and RCA documentation to prevent recurrence.
• Execute rack and stack operations for 50+ physical servers — server installation, structured cabling, patch panel management, and asset labelling — following DCIM standards and change management processes.
• Manage end-to-end hardware lifecycle for 100+ servers and network devices — procurement validation, installation, firmware updates, preventive maintenance, and secure decommissioning — reducing procurement-to-deployment time by ~30% through standardised validation checklists.
• Troubleshoot physical server hardware failures — iDRAC/BMC diagnostics, RAID degradation, NIC and HBA issues, disk replacements — reducing hardware-related downtime and escalations by ~20%.
• Track and optimise data center power utilization, cooling efficiency, and environmental parameters (temperature, humidity), applying ASHRAE thermal guidelines to reduce equipment-related incidents.
• Collaborate with Major Incident Management teams on Critical Change Tasks (CCT) and Disaster Recovery (DR) drills, ensuring infrastructure readiness and validated recovery procedures for production systems.
• Author rack elevation diagrams, structured cabling schematics, asset inventory records, and operational SOPs — reducing new engineer onboarding time and ensuring audit-readiness during infrastructure reviews.
