Lead Site Reliability Engineer and Cloud Architect

Designed and maintained multi-region AWS and GCP environments for enterprise financial analytics platforms, supporting a verified 99.99% uptime SLA. Administered more than 30 GKE and EKS clusters using Helm and GitOps, including automated zero-downtime upgrades, HPA/VPA autoscaling, and network policies.

Established SLO/SLI budgets, blameless postmortems, and disaster recovery practices with global stakeholders. Built FinOps programs that reduced cloud compute spend by 20–30%, CI/CD pipelines with Cloud Build, GitHub Actions, and Jenkins, and modular Terraform landing-zone infrastructure. Improved observability with Prometheus, Grafana, and Google Cloud Operations Suite, reducing MTTR by 35%, and developed 30+ automation utilities in Python, Go, and Bash.

Designed CI/CD pipelines using Jenkins, GitHub, Apache Maven, and SonarQube to automate quality gates, artifact versioning, and security scanning. Containerized distributed microservices with Docker, improving development-to-production consistency and increasing application throughput.

Provisioned GCP and AWS infrastructure using Terraform, including Compute Engine, VPC networks, Cloud SQL, EC2, and RDS. Authored Ansible playbooks for OS hardening and configuration management, and automated Kubernetes deployments using manifests, ConfigMaps, Secrets, and ingress controllers.

Architected and stabilized multi-terabyte transactional data pipelines across Azure and GCP services, including BigQuery, Dataproc, and Databricks. Resolved concurrency collisions and metadata bottlenecks in high-frequency data workloads using partition pruning, commit decoupling, and Z-Order compaction.

Engineered Shared VPC and hub-and-spoke networks, Private Service Connect, cross-region peering, and custom routing tables. Conducted network root-cause analysis with tcpdump and Wireshark, and authored Terraform modules across more than 12 enterprise cloud project and subscription hierarchies.

Administered mission-critical RHEL and CentOS server fleets, including SAN/NAS storage arrays, LUN allocation, and backup automation. Maintained automated build and packaging frameworks using RPM, Make, Shell, Subversion, Git, and Jenkins.

Troubleshot Linux runtime and production stability issues involving CPU and memory saturation, file descriptor exhaustion, and network socket leaks. Coordinated release cutovers with distributed engineering teams and delivery managers while enforcing release quality standards.
