PROFESSIONAL EXPERIENCE

DevOps/SRE Engineer CapitalOne Financial USA June 2025 – Present

• Deployed and managed Amazon EKS clusters with auto-scaling and multi-AZ deployment to support scalable microservices across dev, QA, and production environments.

• Built GitOps-based deployment pipelines using ArgoCD and Helm, ensuring declarative, auditable, and environment-specific infrastructure provisioning for dev, QA, and production stages.

• Automated provisioning and managed AWS resources including EC2, S3, RDS, and VPC using Terraform, AWS CDK, and CloudFormation to deliver reliable, consistent, and fully automated cloud infrastructure.

• Performed root cause analysis (RCA) for application downtime by identifying misconfigured resource requests/limits, failing readiness and liveness probes, and incorrect environment variables in Kubernetes manifests.

• Provisioned and maintained Kafka and RabbitMQ infrastructure, resolved performance and connectivity issues to ensure reliable message delivery across distributed systems.

• Automated Java application deployment using Chef recipes, managing Tomcat configuration, application installation, and runtime environment setup.

• Applied AWS Config rules to enforce security baselines, tightened IAM policies to enforce least-privilege access, and managed secrets using AWS Secrets Manager to maintain compliance.

• Integrated AWS WAF and CloudFront with load balancers to protect APIs from web exploits and DDoS attacks.

• Configured API Gateway endpoints with authentication, rate limiting, and request validation to protect backend services from attacks.

DevOps/SRE Engineer Accenture The Walt Disney Jan 2022 - July 2023

• Developed secure, reusable Terraform modules to automate AWS infrastructure provisioning including VPC, subnets, EKS clusters, EC2 instances, RDS databases, and IAM roles across dev, sandbox, stage, load, and production environments.

• Implemented Jenkins CI/CD pipelines integrated with SonarQube and Nexus to enforce quality standards, manage dependencies, and publish build artifacts.

• Containerized legacy Java applications with Docker and deployed them to EKS and self-managed Kubernetes clusters, lowering infrastructure costs by minimizing virtual machines.

• Set up centralized logging and alerting by integrating ELK stack, CloudWatch and pushed real-time alerts to Slack and PagerDuty, enabling proactive incident response capabilities.

• Managed PostgreSQL and RDS database instances, optimizing query performance, configuring automated backups, and implementing multi-AZ failovers to ensure data availability and durability.

• Maintained 99.9% uptime SLA while handling on-call responsibilities with detailed runbooks, following ITIL processes for incident, change, and problem management.

• Automated snapshot and backup workflows for EC2 and RDS instances using AWS Systems Manager, ensuring complete backup coverage and adherence to daily disaster recovery policies.

• Troubleshot deployment and rollout failures by inspecting ReplicaSets, deployment strategies (Rolling Update), and rollout history, ensuring zero-downtime releases and quick rollback during failures. DevOps Engineer HCL Technologies Coles Jan 2021 - Dec 2021

• Deployed highly available cloud environments using Terraform and AWS CloudFormation, supporting production and staging applications with standardized infrastructure patterns.

• Managed vulnerability and patching activities, resolving critical issues like Log4j and coordinating with security teams to keep systems secure and compliant.

• Implemented security best practices including network policies, pod security policies, and RBAC in Kubernetes to enforce least- privilege access and prevent unauthorized container execution.

• Created S3-backed static websites blended with API Gateway, Route 53, and CloudFront to deliver high-availability patient dashboards with secure and low-latency access.

• Configured Application Load Balancers and Network Load Balancers with health checks and routing policies to distribute traffi c and ensure application availability.

• Designed and implemented blue/green and rolling deployment strategies within Jenkins CI/CD pipelines to reduce downtime and minimize production rollback incidents.

• Automated builds and deployments using Jenkins, Maven, and Shell scripts for Java applications, ensuring consistent delivery pipelines.

DevOps Engineer Synectiks Citibank Jan 2018 - Dec 2020

• Automated configuration and deployment tasks across environments using Ansible playbooks, ensuring consistent infrastructure states in QA, UAT, and production.
