- Collaborated with development teams to enhance application performance and reliability.
- Managed cloud infrastructure to ensure optimal resource allocation and performance.
- Monitored system performance and resolved issues proactively to maintain uptime.
- Performed Pivotal Cloud Foundry (PCF) to Red Hat OpenShift (OCP) migration.
- Infrastructure Modernization: "Led the strategic migration of 200+ microservicesfrom PCF to OpenShift, achieving a 30% reduction in TCO by eliminating proprietary licensing and optimizing resource utilization through Kubernetes-native autoscaling".
- Architecture Refactoring: "Collaborated with development teams to refactor legacy PCF applications, transitioning from Cloud Foundry Buildpacks to Source-to-Image (S2I) and Dockerfile-based builds to enhance portability and developer agility".
- Platform Translation: "Mapped and migrated complex PCF organizational structures (Orgs/Spaces/Quotas) to OpenShift Hierarchical Namespaces and RBAC policies, ensuring consistent security posture and multi-tenancy during the transition".
- Service Binding Migration: "Orchestrated the migration of stateful backing services (MySQL, RabbitMQ) from PCF's Service Broker model to OpenShift Operators and OpenShift Data Foundation (ODF), ensuring zero data loss".
- Observability Parity: "Maintained operational continuity by replacing PCF Healthwatch with a native Prometheus and Grafana stack, developing custom dashboards to monitor cluster health and application performance
- Service Binding Migration: "Orchestrated the migration of stateful backing services (MySQL, RabbitMQ) from PCF's Service Broker model to OpenShift Operators and OpenShift Data Foundation (ODF), ensuring zero data loss".
- Observability Parity: "Maintained operational continuity by replacing PCF Healthwatch with a native Prometheus and Grafana stack, developing custom dashboards to monitor cluster health and application performance
- Migrating the deployment from UCD to harness.
- Spearheaded the migration of 100+ applications from legacy UrbanCode Deploy (UCD) to Harness CD, transitioning from manual XML/JSON-based process configurations to a declarative YAML-based Pipeline-as-Code model".Deployment Velocity & Efficiency: "Accelerated software delivery by 30% by replacing UCD’s complex component-based processes with Harness Template Libraryand standardized deployment workflows across microservices".
- Operational Risk Reduction: "Integrated AI-powered Continuous Verification (CV) in Harness to replace manual verification steps used in UCD, reducing deployment-related risks and slashing Rollback time (MTTR) by 93%".
- Technical Execution AutomationPipeline Translation: "Re-architected deployment pipelines by mapping UCD 'Components' and 'Environments' to Harness Services and Environments, ensuring parity while optimizing for Kubernetes-native deployments".
- Progressive Delivery Implementation: "Modernized release strategies by implementing out-of-the-box Canary and Blue/Green deployments in Harness, eliminating the need for the custom Groovy scripting previously required in UCD".
- Cost & Secret Management: "Consolidated infrastructure secrets from UCD into Harness Secret Manager (integrated with HashiCorp Vault), improving security posture and reducing static credential exposure.
- Developed configuration management scripts for consistent environment setups.
- Facilitated container orchestration using Kubernetes for scalable application management.
- Led design review meetings to align team efforts with client expectations.
- Managed cloud infrastructure using AWS and Azure for various projects.
