Pinnacle Financial Partners — Azure DevOps Engineer Nashville, TN Aug 2024 – Present

• Automated AWS environment builds for IBM WebSphere, MQ, and Oracle workloads using Terraform, Terragrunt, and Ansible, reducing provisioning time and standardizing infrastructure for core banking platforms.

• Built CI/CD workflows with Harness and GitHub Actions for microservices running on Kubernetes and OpenShift, reducing manual deployment effort and improving release consistency across banking applications.

• Embedded BDD-style automated test coverage into Jenkins pipelines, helping validate financial application changes before release and lowering the risk of rollback during production windows.

• Deployed Java and .NET web applications through cloud-based delivery pipelines integrated with Application Insights and CloudWatch, tightening post-deployment feedback loops for customer-facing banking services.

• Designed Azure infrastructure patterns using Azure DevOps, Virtual Machines, Storage, and networking services, supporting secure and stable delivery for online and mobile banking workloads.

• Standardized GitLab branching, merge, and release workflows across Dev, QA, and UAT teams, reducing merge conflicts and improving coordination for shared application components.

• Built release health and defect-tracking dashboards for engineering and product stakeholders, improving visibility into pipeline status, issue prioritization, and release readiness.

• Coordinated production deployments during approved change windows with developers, QA, and security teams, following controlled rollout and rollback procedures for high-value banking services. Centene — DevOps Engineer Hyderabad, India Jan 2024 – Jul 2024

• Built MLOps pipelines with Kubeflow on GCP and Azure, making model training, validation, and production promotion more repeatable for healthcare data science teams.

• Configured Azure Site Recovery and Azure Backup for critical healthcare services and executed disaster recovery drills with zero downtime, validating failover and failback readiness for clinical applications.

• Integrated SonarQube into existing CI/CD pipelines, shifting static code analysis earlier in the delivery lifecycle and reducing critical code issues reaching production.

• Applied NSX-T micro-segmentation to isolate sensitive patient-data workloads, strengthening east-west traffic controls and supporting regulated healthcare environments.

• Implemented Redis caching for EHR-related workflows, improving response times for clinician-facing queries and reducing pressure on backend databases during peak usage.

• Built monitoring and alerting with Dynatrace, Prometheus, Grafana, and Azure Monitor, improving production visibility and reducing mean time to detection for operational incidents.

• Partnered with data science, security, and clinical operations teams to align infrastructure, CI/CD, and MLOps changes with patient-data privacy requirements and internal governance controls. Cognizant — DevOps Engineer Hyderabad, India Aug 2022 – Aug 2023
