Drive build and release automation for core payment and account servicing microservices on AWS, maintaining Jenkins and GitHub Actions pipelines that run build, test, security scan, and deployment stages across development, UAT, and production. Manage Amazon EKS clusters provisioned via Terraform and Helm across multiple AWS accounts, standardizing VPC, IAM, and networking so teams get consistent environments. Embed DevSecOps controls (static code analysis, container image scanning) and use Vault-based secrets management with RBAC, reducing critical/high vulnerabilities reaching production by 45%. Orchestrate GitOps releases using Argo CD with blue-green and canary rollouts plus automated rollback, cutting deployment lead time by 35%. Instrument monitoring and alerting with Prometheus, Grafana, and Splunk; participate in on-call and root cause analysis.

Supported cloud infrastructure automation for enterprise managed services clients by developing Terraform modules and Ansible playbooks for Azure and AWS, replacing manual provisioning with version-controlled code. Reduced environment provisioning time by 40% by templating repeatable infrastructure patterns for compute, storage, networking, and access policies. Built and maintained GitLab CI and Jenkins pipelines for containerized applications, adding automated unit tests, artifact publishing, and deployment stages. Containerized applications with Docker and deployed them on Kubernetes using Helm charts for environment-specific values, config maps, and secrets. Implemented monitoring and log aggregation dashboards with Prometheus, Grafana, and ELK, reducing mean time to detect production issues by 30%. Wrote Python and Bash scripts for operations, and documented runbooks for handover and on-call.

Managed AWS infrastructure for client product engineering engagements including EC2, S3, VPC, IAM, load balancers, and auto scaling across development, QA, staging, and production. Designed and maintained Jenkins CI/CD pipelines for compile, test, artifact management, and multi-environment deployments, reducing manual release effort by 50%. Containerized microservices with Docker and orchestrated them on Kubernetes using Helm charts with environment-specific configuration and rolling update strategies. Built reusable Terraform modules for networking, compute, and IAM to keep environments consistent and repeatable. Automated configuration management, patching, and server hardening with Ansible playbooks. Implemented monitoring and centralized logging with Prometheus, Grafana, and ELK, improving visibility and reducing mean time to resolution by 35%. Performed Linux administration and participated in incident management/on-call with root cause analysis and Agile release readiness reviews
