Project 2- TPG VHA

• Implemented CI/CD pipeline pipeline using Git, Jenkins, and Docker, reducing deployment time by 40% and improving release cycle frequency by 30%, significantly accelerating time-to-market for application updates.
• Developed Ansible YAML scripts to automate remote server configuration, reducing manual configuration time by 60% and ensuring uniformity across environments.
• Automated Kubernetes operations and container deployments using Jenkins-based CI/CD pipelines, Helm templates, and custom scripts, improving container orchestration efficiency by 45% and reducing manual intervention in production deployments.
• Designed and implemented cloud security measures, including VPCs, network security controls, VPC peering, VPNs, MFA, and private disk encryption, ensuring compliance with industry security standards and reducing potential security vulnerabilities
• Integrated Prometheus for continuous monitoring of infrastructure and application health, providing real-time performance data. Used Grafana to create interactive dashboards, enabling proactive issue resolution.
• Utilized Grafana for creating customizable, interactive dashboards for visualizing infrastructure and application performance.
• Automated the creation and scaling of MongoDB clusters on a PaaS platform, ensuring 99.99% availability, scalability, and reliability of database services, which contributed to improved system performance and faster data retrieval times.
• Version Control & Collaboration: Managed source control and versioning using Git, facilitating seamless collaboration across cross-functional teams, maintaining code integrity and enabling smoother rollbacks in production environments.

Project 1 AMX OC

• Managed 15+ data centers and over 1000 servers, supporting VNF application deployment, scaling, and ongoing maintenance, ensuring smooth operation and service delivery.
• Administered 3-tier Spine-Leaf and Border-Leaf architecture with VXLANs to provide large-scale, resilient infrastructure solutions.
• Configured DC gateway integration leveraging BGP, VRRP, VRF, and VLANs to enable efficient and secure communication between data centers.
• Provisioned and managed cloud resources in OpenStack, including instances, snapshots, volumes, templates, and network configurations, improving resource allocation and scalability.
• Integrated multiple storage backends such as ScaleIO and Nexenta with OpenStack, ensuring reliable and scalable storage management.
• Optimized network virtualization by leveraging OpenDaylight as an SDN controller, enhancing network management and automation.
• Automated key infrastructure tasks with Python, Bash, and Ansible, leading to a 50% reduction in hardware usage (HP & Dell Servers) and streamlining operations.
• Developed detailed technical documentation (LLD, pre-deployment checklists, risk/impact analysis) to ensure smooth project deployment and risk mitigation.
• Monitored infrastructure performance continuously, ensuring high availability and reliability across the entire network.
