Prashanth

Results-driven Senior DevOps Engineer with 6+ years of ownership in designing, automating, and operating cloud-native platforms on AWS and Kubernetes for large-scale retail and enterprise systems. Proven track record of owning end-to-end infrastructure lifecycle, CI/CD pipeline architecture, DevSecOps shift-left security programs, and SRE reliability practices including SLO/SLI definition and error-budget management. Delivered $40K+ annual cloud cost savings, improved platform availability to 99.95%+, and reduced deployment lead time by 70% through Infrastructure as Code, GitOps automation, container orchestration, and observability engineering.

Expert in Terraform, Kubernetes, Docker, Helm, Jenkins, GitLab CI/CD, ArgoCD, GitHub Actions, Prometheus, Grafana, and cloud security hardening with AWS WAF, GuardDuty, and IAM least-privilege policies.

Senior DevOps Engineer (SRE) - Walmart Global Tech - Bengaluru, India

(2022-09)

• Owned end-to-end infrastructure architecture for high-traffic retail microservices across 15+ environments by building reusable Terraform modules, reducing environment provisioning time from days to under 2 hours and cutting manual effort by 65%.
• Owned EKS cost-optimization initiative: right-sized workloads, implemented Cluster Autoscaler and Spot-instance strategies, delivering $40K+ annual AWS compute savings while maintaining performance SLAs during peak retail traffic including Black Friday and festive sales.
• Owned and led migration of legacy on-premise services to AWS EKS, improving scalability for seasonal demand spikes and eliminating capacity-related slowdowns that previously impacted checkout conversion rates.
• Architected and owned GitOps-based CI/CD pipelines using GitLab CI, ArgoCD, and Helm, increasing deployment frequency from weekly to multiple daily releases and reducing deployment lead time by 70%.
• Owned deployment strategy transformation by introducing automated canary and blue-green deployment patterns, cutting change-failure rate and enabling instant rollback to reduce customer-facing incident windows during releases.
• Owned Policy as Code implementation via OPA/Gatekeeper and centralized secrets management with HashiCorp Vault and AWS Secrets Manager, eliminating hardcoded credentials across pipelines and enforcing compliance guardrails.
• Owned cloud security hardening initiative: implemented AWS WAF, GuardDuty, Security Hub, and IAM least-privilege policies, closing audit gaps and achieving zero critical findings in internal security reviews.
• Owned SRE observability framework: defined SLOs, SLIs, and error budgets for business-critical services; built golden-signal dashboards (latency, traffic, errors, saturation) in Grafana, reducing Mean Time To Detect (MTTD) by 45%.
• Owned incident response automation: engineered self-healing infrastructure with Kubernetes probes, automated runbooks, and PagerDuty escalation policies, lowering Mean Time To Recovery (MTTR) and improving overall platform availability to 99.95%+.

DevOps Engineer - Quess Corp - Bengaluru, India

(2020-10 - 2022-09)

• Owned build and maintenance of Jenkins and GitLab CI/CD pipelines for multiple application teams, automating build, test, and deployment workflows and reducing manual release effort by 50%.
• Owned containerization strategy for legacy applications using Docker and deployed to self-managed Kubernetes clusters, improving environment consistency and eliminating 'works-on-my-machine' deployment failures.
• Owned Infrastructure as Code automation using Terraform and Ansible for repeatable provisioning across Dev, QA, and Production environments, reducing configuration drift and standardizing infrastructure delivery.
