● Designed and deployed enterprise GitLab platform architecture serving 10,000+ users, engineering highly available components (Gitaly, PostgreSQL, Redis) with a focus on scalability across multiple data centers.

● Led migration of CI/CD workloads from XebiaLabs to GitLab across three data centers (DC1, DC2, DC4), consolidating tooling, reducing dependency on deprecated platforms, and improving pipeline efficiency.

● Architected end-to-end CI/CD pipelines integrating Bitbucket, GitLab, Jenkins, and Ansible Tower to automate build, test, and deployment workflows across multiple environments including QA, STG and Production.

● Managed containerized workloads on Kubernetes platforms, deploying applications using Helm charts, defining custom resource definitions (CRDs), and enforcing Kubernetes network policies; applied this experience to evaluate and design Amazon EKS-based architectures.

● Drove service mesh evaluation (Kong), assessing service-to-service communication patterns, traffic management, and network policies to support the organization’s microservices architecture strategy.

● Designed AWS cloud networking and security architectures, including VPCs, IAM policies, security groups, and network segmentation, applying on-prem network and security best practices to cloud environments.

● Automated infrastructure provisioning and configuration management using Terraform and Ansible, supporting resource lifecycle management and centralized log collection across distributed environments.

● Collaborated with security teams to align infrastructure and CI/CD practices with CIS Benchmarks and NIST security frameworks, supporting cloud security posture initiatives.

● Served as SME for the vSphere 7 to vSphere 8 infrastructure migration, modernizing the virtualization platform to improve performance, scalability, and long-term supportability.

● Implemented observability using Splunk and Grafana, building dashboards and metric-driven alerts to proactively identify issues and improve application reliability.

● Participated in 24 7 on-call rotations, performing root cause analysis on production incidents and driving resolution across infrastructure, network, and application layers.
