- Executed zero-downtime Amazon EKS upgrades (Control Plane, Node Groups, CoreDNS, VPC CNI, and add-ons) across 20+ production EKS clusters, improving security, stability, and Kubernetes feature adoption.
- Owned the GitLab CI/CD platform as GitLab Administrator, driving platform-wide CI/CD improvements by designing reusable pipeline templates, integrating Terraform-based infrastructure provisioning, standardizing CI/CD pipelines to eliminate operational toil and improve the Developer Experience (DevEx), optimizing build and deployment performance, establishing CI/CD best practices, and mentoring 40+ engineering teams to improve developer productivity, increase deployment reliability, and accelerate time-to-production.
- Reduced deployment time by 80%+ by transforming fragmented deployment workflows into One-Click deployment pipelines for major and minor releases, minimizing manual effort and deployment failures.
- Led production release management for major and minor releases, enabling RBAC-based self-service deployments through Ansible Tower and improving release velocity across engineering teams.
- Developed reusable Terraform modules to provision and manage AWS infrastructure, ensuring consistency, reducing configuration drift, and accelerating environment provisioning.
- Developed a Go-based automation platform for monitoring and managing SSL/TLS and GPG certificates, automating certificate lifecycle management, proactive expiration alerts, and end-to-end certificate rotations with enterprise CAs including DigiCert and GoDaddy for critical banking partners (e.g., Citi, JPMC, BMO), eliminating manual operational effort.
- Saved $20K+ per month in AWS infrastructure costs by optimizing NAT Gateway traffic through caching strategies and a DNAT-based proxy architecture, significantly reducing network egress charges while maintaining application performance.
- Reduced Amazon ECR storage costs by 40% by implementing automated lifecycle policies, image retention strategies, and IAM governance, improving cost efficiency while strengthening security and compliance.
- Led the migration of Jenkins CI/CD infrastructure from on-premises to AWS, improving scalability, reliability, and platform availability for growing engineering teams.
- Designed and optimized monitoring and alerting for availability, latency (p50/p95/p99), error rates, resource utilization, and infrastructure drift, enabling faster incident detection and reducing MTTR.
- Partnered with application teams to take microservices from design to production, providing Kubernetes platform engineering, CI/CD automation, infrastructure provisioning, and operational support.
