Bridging 5G RAN and Cloud Native Architecture

I am driven by the challenge of evolving traditional telecommunications into scalable, cloud-native environments. Having started my career integrating 5G and LTE networks, I saw the bottlenecks of manual configuration firsthand. This motivated me to pivot into DevOps, where I now architect bare-metal Kubernetes platforms and AI-ready infrastructure to eliminate inefficiencies through automation.

Core Capabilities

Bare-Metal Orchestration

Deploying and managing Red Hat OpenShift (OCP 4.x) and Kubernetes on bare-metal servers utilizing IPI/UPI and Single Node OpenShift (SNO) strategies.
AI Infrastructure

Commissioning massive AI GPU clusters (NVIDIA H100, GH200) and integrating GenAI observability stacks. NVIDIA NCA-AIIO Certified.
Infrastructure as Code

Automating hardware provisioning and configuration management using Terraform, Ansible, Python, and Bash, reducing delivery times by up to 40%.
DevOps

Optimizing CI/CD pipelines with GitLab CI and ArgoCD to streamline the migration of containerized applications and ensure zero-downtime deployments.

Infrastructure Projects

Highly Available Kubernetes Infrastructure

Automated provisioning of a 3-node Kubernetes cluster. Built using Terraform and Ansible to ensure rapid, repeatable, and scalable deployments across diverse environments.
