About

I am a passionate Site Reliability & DevOps Engineer with 9+ years of experience designing, automating, and optimizing cloud infrastructure to enable fast, reliable, and secure product delivery. My core focus is on building resilient systems, from automating CI/CD pipelines to scaling cloud-native applications and making infrastructure developer-friendly, stable, and efficient. I thrive on solving complex problems, learning new technologies, and translating them into tangible improvements for teams and organizations. I have worked extensively across Linux, AWS, GCP, Kubernetes, Terraform, Terragrunt, Ansible, Jenkins, Helm, Prometheus, HashiCorp Vault, Istio, Nginx, Spinnaker, ELK, Kafka, and OPA, with hands-on experience in Python (Flask, Kopf Operator) for automation and operator development. Recently, I have started exploring the intersection of DevOps and AI/LLM technologies to drive intelligent automation. Certifications: RHCSA | RHCE | AWS Solutions Architect | CKA
