About Me

With 4+ years of hands-on experience, including my current role at TATA CONSULTANCY SERVICES (TCS), I view infrastructure not as static servers but as dynamic, version-controlled code. My philosophy is rooted in the continuous lifecycle: bridging the gap between development and operations.

I specialize in designing resilient CI/CD pipelines, orchestrating complex workloads on Kubernetes and Red Hat OpenShift, and eliminating configuration drift through Terraform and Ansible automation.

Kubernetes EKS OpenShift Terraform Ansible ✦ Actively seeking new opportunities

What I Can Do

Architect Cloud Solutions

Designing highly available, scalable infrastructure on AWS and building robust Kubernetes (EKS) and OpenShift clusters from the ground up.

Automate Pipelines

Creating zero-touch CI/CD workflows using Jenkins and GitHub Actions, enabling seamless and secure multi-environment artifact promotions.

Infrastructure as Code

Eliminating manual setups and configuration drift with modular, reusable Terraform scripts and automated Ansible playbooks.

Secure & Monitor

Enforcing DevSecOps with HashiCorp Vault, Snyk, and SonarQube, while proactively monitoring via Grafana & Prometheus.

  • Architected end-to-end CI/CD pipelines using Jenkins and GitHub Actions, integrating SonarQube, JFrog, and Helm for traceable artifact promotion across 6+ environments.
  • Managed Red Hat OpenShift (RHOCP 4.x) across strict Dev to QA to UAT to Stage to PROD workflows including Routes, DeploymentConfigs, BuildConfigs and ImageStreams.
  • Deployed HashiCorp Vault Operator and Agent Injector — zero-touch secrets injection eliminating all hardcoded credentials across all CIBC GOW environments.
  • Accelerated infrastructure provisioning by 75% via modular Terraform and Ansible playbooks, reducing MTTD by 40% with Grafana/Prometheus alerting.

DevOps Engineer

Tata Play — DTH Media Platform (via TCS)

Mar 2022 – Apr 2024
AWS EKS Kubernetes Jenkins Terraform Ansible
  • Managed vanilla Kubernetes clusters on AWS EKS, handling node scaling, persistent volumes (EBS/EFS), namespace management, and RBAC for 10+ microservices.
  • Achieved 99.5% uptime SLA and reduced AWS infrastructure costs by 30% through just-in-time provisioning via CronJobs and Lambda scheduling.
  • Configured HPA and Cluster Autoscaler to dynamically reduce over-provisioning costs by 35% in Production and Stage environments.
  • Reduced incident downtime by 70% through automated alerting scripts and documented remediation playbooks with clear escalation paths.
