Led the migration of microservice-based applications from vCenter on-premises infrastructure to the OpenShift Container Platform, modernizing deployment architecture through containerization and cloud-native technologies. Achieved significant improvements in scalability, security, and operational efficiency, with a focus on performance optimization and compliance.

• Integrated Consul Service Mesh with OpenShift to manage and secure microservices-based applications, improving service discovery, load balancing, and resiliency across the platform.
• Directed the end-to-end migration, moving applications from Tier 6 to Tier 3 of RPO (Recovery Point Objective) and RTO (Recovery Time Objective), improving disaster recovery capabilities by 50%.
• Enhanced scalability, resilience, and operational agility by implementing automated CI/CD pipelines using Jenkins and leveraging Ansible Tower for configuration management.
• Implemented and optimized Consul Service Mesh to secure microservices communication using service intentions, ACLs, and mutual TLS (mTLS) across multi-datacenter setups, ensuring high availability, security, and real-time configuration updates via key/value pairs.
• Automated SSL/TLS certificate management by integrating Cert Manager and Venafi, reducing manual certificate renewals by 80%.
• Deployed Proof of Concept (POC) environments prior to development (DEV), ensuring infrastructure readiness and addressing scalability issues early.
• Integrated OpenShift logging with Splunk, enabling comprehensive real-time monitoring, faster troubleshooting, and improving system uptime by 20%.
• Focused on compliance, security, and performance optimization throughout the migration process, ensuring a smooth transition to the OpenShift platform.
• Secured the platform by integrating HashiCorp Vault for managing sensitive information, such as application secrets and service account credentials, enforcing strict encryption protocols.
• Implemented advanced encryption techniques to safeguard URLs, service account credentials, and other sensitive data, ensuring protection throughout the deployment lifecycle and prior to usage.
• Managed traffic flow using Local Traffic Manager (LTM) and Global Traffic Manager (GTM), improving performance and high availability across distributed environments by 30%.
• Enhanced Service Mesh features to support multi-datacenter high availability, enable API metrics gathering and reporting, maintain clean key/value data for configuration, and integrate enhanced role -based authentication.
• Introduced Dynatrace as an application performance management tool to monitor and optimize application performance metrics.
• Leveraged tools like Kustomize and Helm to manage application configurations across multiple environments.
• Integrated Dynatrace with OpenShift to enhance application performance observability, enabling real -time monitoring,proactive identification of performance bottlenecks, and resolution of resource constraints, resulting in improved reliabilit yand optimized resource utilization.
• Implemented Horizontal Pod Auto scaler (HPA) and Vertical Pod Auto scaler (VPA) in Kubernetes/OpenShift to dynamicallymanage application scaling based on workload demands. Optimized resource utilization and ensured application performance by configuring autoscaling policies for CPU, memory, and other custom metrics, enabling seamless handling of fluctuating traffic patterns.
• Spearheaded the migration and modernization of a Python-based application leveraging Flask and FastAPI technologies to the OpenShift Container Platform, enhancing scalability, reliability, and efficiency.
• Managed and deployed Java-based microservices applications built with the Spring Framework on the OpenShift Container Platform, leveraging Bootstrapping architecture to ensure seamless scalability, enhanced performance, and streamlined deployment processes. Optimized application orchestration using OpenShift-native capabilities, achieving robust service discovery and efficient resource utilization.
• Documented processes, deployment strategies, and workflows on the internal wiki, ensuring consistent knowledge sharing and improved team onboarding.

• Delivered technical documentation and presentations, ensuring clear communication with both technical and business stakeholders.

Acquired an understanding of AWS Migration Hub, AWS Server Migration Service (SMS), and AWS Database Migration Service (DMS). Offered technical support to the migration team in resolving arising issues, ensuring progress in project execution.

• Improved security standards by 20% during migration processes through the integration of AWS security practices.
• Ensured consistent software delivery by automating code deployment at various stages of product development and testingthrough Continuous Deployment (CD) pipeline configuration.
