PROFESSIONAL EXPERIENCE

Sr. DevOps Engineer, Hopper — New York City, NY

Oct 2024 - Present

●Led a cross-functional team of 15 engineers to develop a disaster recovery plan, aiming restoration of critical operations within 24 hours. Conducted risk assessments, staff training, implemented new backup and security procedures and tools—reducing potential revenue loss by 35%.

●Led efforts to align infrastructure and deployment practices with ISO 27001, SOC 2, GDPR, and PCI DSS requirements, embedding security and compliance into DevOps workflows by automation, policy-as-code, and continuous monitoring.

●Co-piloted with the Cloud Architect on capacity planning and cloud cost optimization project. Analyzed usage patterns with CloudWatch and Cost Explorer, right-sized VMs and DBs, decommissioned idle resources, configured S3 lifecycle policies, and introduced SCPs to prevent provisioning of oversized compute and database resources.

●Managed Java dependency conflicts and build failures by analyzing Gradle configurations and collaborating with developers to enforce dependency versioning best practices, improving CI/CD pipeline reliability and reducing build errors by 30%.

●Created a comprehensive, clear, and accessible knowledge base using Notion that improved team alignment and decreased onboarding time for the new team members.

DevOps Engineer, Hopper — New York City, NY

Jun 2021 - Oct 2024

●Built and maintained CI/CD pipelines with Jenkins and ArgoCD, enabling faster and more secure deployments for microservices—integrated Gradle, Docker, SonarQube (Static Application Security Testing), and Trivy (container scanning) for full pipeline coverage.

● Deployed and updated EKS clusters with node groups using Terraform, increasing deployment frequency by 10%.

●Optimized Kubernetes resource usage by configuring Cluster Autoscaler and Horizontal Pod Autoscaler with CPU/memory and custom metrics, reducing overprovisioning and cutting cloud costs by scaling pods and nodes based on actual workload.

●Fixed hidden pod failures and improved uptime by setting up Liveness/Readiness probes and Pod Disruption Budgets—led to a 25% drop in unexpected downtime.

●Provided seamless code deployments via applying canary, blue-green, and RollingUpdate strategies utilizing Kubernetes services and Ingress Controller (Ingress with annotations and pods with termination grace period).

●Designed and deployed secure and optimized Docker images, leveraging multi-stage builds to enhance efficiency and minimize image sizes by up to 50%.

●Monitored system health and performance, troubleshooted operational issues, and enforced security best practices using Prometheus, ELK Stack, CloudWatch, CloudTrail, AWS Service Control Policies (SCPs), IAM Roles.

●Provisioned and managed cloud infrastructure using Terraform to implement infrastructure changes and improve system reliability.

●Built a monitoring and alerting stack using Prometheus, Alertmanager, and Grafana—visualized pod and service metrics across Kubernetes clusters and configured alert rules to catch high memory and CPU usage early, reducing incident response time by 16%.

●Automated recurring processes using AWS Lambda and Python, reducing manual intervention and improving system efficiency.

●Used AWS Glue, Athena and QuickSight data to analyze infrastructure historical performance, which helped the team adjust scaling settings for better stability and cost-efficiency. Gathered information helped to create an ML model to predict traffic spikes.

Jr. DevOps Engineer, Grubhub — Chicago, IL

May 2018 - Jun 2021

●Implemented private networks using VPC, security groups, route tables, internet, and NAT gateways. Improved connectivity through VPC peering across multiple VPCs.

●Implemented cloud firewalls using NACLs and Security Groups to strengthen network security and control traffic flow.

●Set up EKS and ECS clusters to support containerized workloads, using Fargate where possible to simplify management and lower operational overhead.

●Implemented load balancers with ELB to distribute traffic efficiently between private and public subnets. Utilized Route 53 to create records for exposing services to public networks, ensuring reliable access and scalability.

●Achieved a 15% reduction in storage costs by optimizing Amazon S3 lifecycle policies, specifically through configuring S3 Intelligent-Tiering and Deep Archive options.

●Resolved CPU and memory bottlenecks and proactively suggested enhancements to boost performance in future implementations.

●Integrated Kubernetes cluster alerts into Slack workspaces, improving real-time monitoring and response time by up to 5%.

●Configured AWS EC2 virtual machines by implementing Ansible playbooks and created a custom AWS AMI to optimize CPU performance.

●Deployed and configured EC2 instances, developed custom Amazon Machine Images, and integrated databases with RDS and Secrets Manager for secure and efficient data management.
