Own end-to-end reliability of 3 production EKS clusters (150+ applications, 200+ nodes) supporting critical microservices in a healthtech environment, orchestrated through 200+ Jenkins and ArgoCD pipelines. • Drove a 30-40% improvement in deployment speed by redesigning CI/CD pipelines for parallel execution and eliminating manual bottlenecks. • Introduced rolling-update and blue-green deployment strategies alongside improved readiness/liveness probes and graceful shutdown handling, reducing rollout failures. • Led zero-downtime EKS cluster upgrades with no critical incidents, coordinating with application teams on migration timing. • Lowered MTTR by approximately 30% by building faster production-debugging workflows and proactive alerting on top of the existing observability stack. • Reduced infrastructure setup time by approximately 50% by automating provisioning workflows in Terraform. • Hardened platform security and scaling by rolling out RBAC across ArgoCD and Jenkins, adopting Karpenter for node-level autoscaling and KEDA for event-driven workload autoscaling, and integrating External Secrets Operator with AWS Secrets Manager. • Act as primary on-call responder for critical applications, owning root cause analysis and post-incident reviews.

Owned DevOps strategy and delivery for 30+ production-grade platforms spanning 30+ client AWS accounts across fintech, edtech, and AI, serving as the senior technical point of contact for infrastructure decisions. • Architected highly available AWS infrastructure (EKS, ECS, EC2, Lambda) with API exposure via Amazon API Gateway and Kong API Gateway, CloudFront/Route 53 for global, low-latency delivery, AWS PrivateLink for cost-efficient private connectivity, and AWS RAM for secure cross-account resource sharing. • Standardized infrastructure provisioning by building reusable Terraform and CloudFormation modules adopted across client projects, reducing repeat setup work. • Introduced GitOps workflows using ArgoCD across client platforms, improving deployment traceability and giving teams reliable one-click rollback. • Directed AWS cost optimization initiatives across multiple client accounts, identifying and eliminating unnecessary cloud expenditure. • Introduced Istio service mesh and OpenTelemetry-based tracing to improve service-to-service observability across client platforms. • Mentored junior and mid-level engineers, set technical standards for CI/CD and observability, and led cross-functional coordination between engineering, client stakeholders, and delivery teams.

About

Platform-focused DevOps Engineer with 4+ years of experience designing, automating, and operating production cloud platforms across AWS and Kubernetes. AWS Certified DevOps Engineer – Professional, with hands-on ownership of Kubernetes (EKS) and ECS-based systems, CI/CD pipelines (CodePipeline, Jenkins, ArgoCD), and observability stacks (Prometheus, Grafana, Loki, ELK) across fintech, edtech, AI/ML, and healthtech platforms. My work spans individual-contributor execution to leading DevOps delivery for 30+ production platforms spanning 30+ client AWS accounts, and mentoring engineering teams — with measurable gains in deployment speed, MTTR, infrastructure provisioning time, and cloud cost efficiency. Core areas: • AWS: EKS, ECS (Fargate & EC2), EC2, Lambda, RDS, Aurora (PostgreSQL), ElastiCache (Redis), OpenSearch, API Gateway, Kong API Gateway, CloudFront, Route 53, CloudFormation, CodePipeline, ECR, S3, IAM, VPC (PrivateLink, RAM), Secrets Manager, CloudWatch, AWS CLI • Kubernetes ecosystem: Docker, Helm, ArgoCD (GitOps), Karpenter, KEDA, Istio • CI/CD: AWS CodePipeline, CodeBuild, CodeDeploy, Jenkins, GitLab CI, GitHub Actions • Infrastructure as Code: Terraform, CloudFormation • Observability: Prometheus, Grafana, Loki, ELK, CloudWatch, OpenTelemetry • Security: IAM, RBAC, VPN, Network Policies, External Secrets Operator, AWS Secrets Manager • Scripting: Python, Bash, Linux Certifications: AWS Certified DevOps Engineer – Professional | AWS Generative AI Essentials Sarvam.ai — Contributed to a one-time infrastructure setup as part of the platform team: a GPU-enabled AI/ML EKS cluster provisioned for 100+ AI applications across 500+ nodes, including dedicated GPU node pools. CommerceIQ — Contributed to a one-time EKS platform setup as part of the infrastructure team, provisioning for 100+ applications across 2000+ nodes with HPA configured to auto-scale up to 100 pods per deployment at peak load. Vouchargram — Managed 10 ECS clusters supporting 100+ applications, with API Gateway, Auto Scaling Groups, and CodePipeline-driven deployments. Reward360 — Ran 5+ ECS clusters supporting 100+ applications with automated CodePipeline deployments. New Street Technology (NST) — Set up 3 EKS clusters running 100+ applications with ArgoCD and Jenkins pipelines, using HashiCorp Vault for secrets management. Zaggle — Optimized CI/CD pipelines and reduced cloud costs. BetterPlace — Implemented DevOps automation for HR-Tech platform. Construction.ai — Provisioned infrastructure for analytics workloads.
