DevOps Engineer, Expedia Aug 2023 – Present, TX

• Automated AWS (EKS, Lambda, S3) and GCP infrastructure using Terraform and CloudFormation, reducing provisioning delays by 45% and enabling faster go-to-market for travel applications.

• Built and optimized CI/CD pipelines with Jenkins, GitHub Actions, and Spinnaker, reducing build times by 30% and accelerating release cycles for global booking systems.

• Managed Kubernetes (EKS) clusters supporting high-traffic travel services, ensuring zero-downtime deployments and improving application reliability during seasonal traffic spikes.

• Implemented Datadog, Prometheus, Grafana, and Splunk dashboards to monitor booking and payment platforms, reducing Mean Time to Recovery (MTTR) by 40%.

• Conducted chaos engineering experiments to identify resilience gaps, strengthening fault tolerance and improving system availability for millions of daily user transactions.

• Partnered with product and developer teams to build self-service deployment pipelines, reducing operational bottlenecks and empowering teams to deploy code independently.

• Optimized auto-scaling strategies for search and booking microservices, ensuring performance stability during peak holiday traffic while cutting cloud costs by 18%.

• Secured infrastructure by enforcing PCI and GDPR compliance, applying system hardening, and embedding automated compliance checks in CI/CD workflows.

• Migrated legacy monolithic booking services into microservices on AWS EKS, reducing release complexity and improving scalability across multiple Expedia brands.

• Automated cost optimization scripts using Python and AWS SDK, identifying underutilized resources and saving ~20% in monthly cloud spend.

• Supported global on-call rotations, proactively resolving incidents across distributed environments, ensuring uninterrupted availability for travelers in 30+ countries.

• Improved team collaboration by documenting best practices in Confluence and managing sprints in Jira, streamlining delivery timelines and aligning DevOps goals with business objectives. DevOps Engineer, Accenture June 2019 – Oct 2022, India

• Automated multi-cloud deployments across AWS (EKS, Lambda, S3) and GCP (GKE, Compute Engine) using Terraform and Python, reducing provisioning time by 50% and accelerating client onboarding.

• Built and maintained CI/CD pipelines with Jenkins and GitLab CI/CD, enabling faster and more reliable releases for multi-service applications, which improved delivery speed for client projects.

• Managed Kubernetes clusters and implemented Istio service mesh, ensuring reliable inter-service communication and enhancing system resilience during peak booking traffic.

• Configured ELK Stack and Splunk for centralized logging, allowing proactive troubleshooting and reducing incident resolution times, which minimized downtime for business-critical applications.

• Developed automation scripts in Python, Ansible, and Chef, ensuring consistent configurations across hybrid environments and significantly reducing environment drift and human error.

• Deployed Prometheus and Grafana dashboards, providing real-time visibility into performance metrics and improving Mean Time to Recovery (MTTR) by 35% across client-facing platforms.

• Partnered with QA teams to integrate Selenium, JUnit, and TestNG into CI/CD pipelines, increasing test coverage and reducing production defects, resulting in more stable customer releases.

• Strengthened infrastructure security by applying hardening practices across Linux and Windows servers, ensuring compliance with client regulatory standards and reducing vulnerabilities.

• Optimized PostgreSQL and MongoDB databases, improving query performance and maintaining high availability during traffic spikes, which improved user experience for large-scale client applications.

• Designed and implemented disaster recovery strategies for cloud-native applications, ensuring uninterrupted service availability and meeting strict SLA requirements for enterprise clients.

• Collaborated using Jira and Confluence for agile project management and documentation, improving workflow transparency and enabling more efficient cross-team coordination.

• Improved system stability by fine-tuning Linux (Ubuntu, Debian) and Windows environments, reducing unplanned outages and cutting down repeat support tickets by operations teams. EDUCATION
