What I'm looking for

I seek senior DevOps/Cloud roles to automate infrastructure, build resilient CI/CD pipelines, and implement observability on AWS/GCP, preferably modernizing telecom systems or scaling microservices.

I am a DevOps & Cloud Engineer with 16 years of total professional experience, including 5+ years focused on cloud automation and 10+ years in telecom infrastructure and operations. I specialize in bridging legacy telecom systems with cloud-native solutions.

I have automated cloud infrastructure provisioning on AWS and GCP using Terraform and Ansible, cutting setup time by 60%. I design and operate CI/CD pipelines with Jenkins, GitHub Actions, and ArgoCD, and improved release cadence from weekly to daily through automated testing and rollback strategies.

I manage production Kubernetes clusters (EKS/GKE) and deploy containerized microservices with Helm and Docker, ensuring zero-downtime deployments. I built observability stacks with Prometheus, Grafana, CloudWatch and ELK, which reduced incident response time by roughly 40%.

I hold cloud and container certifications and a Diploma in Electronics & Communication (Government Polytechnic Kanpur, 2008). I am committed to building reusable IaC modules, automating operational playbooks, and helping organizations modernize infrastructure while maintaining production reliability.
