⚡ About Me


I'm a DevOps & Cloud Infrastructure Engineer specializing in building, automating, and securing production-grade cloud environments. With deep expertise in Kubernetes orchestration, Azure cloud architecture, and CI/CD pipeline engineering, I design infrastructure that is resilient, scalable, and cost-optimized.

My engineering philosophy centers on infrastructure as code, zero-downtime deployments, and shift-left security — ensuring every system I build meets enterprise reliability standards from day one. I work across the full infrastructure lifecycle: from provisioning VMs and networking in Azure to deploying containerized applications with Helm, Nginx Ingress, and automated pipelines.

I thrive at the intersection of platform engineering and application delivery, bridging the gap between development teams and production environments with robust automation and observability.

🚀 Featured Projects

⚙️ Enterprise Kubernetes Platform — Azure Private Cluster

Production-grade Kubernetes infrastructure on Azure with private networking, Ingress-Nginx, MetalLB load balancing, and Fortinet VPN integration for secure hybrid connectivity.

Aspect Details
Stack + Ingress-Nginx · MetalLB · Cert-Manager
Scale Multi-node cluster with horizontal pod autoscaling
Networking Private cluster · DNAT via Fortinet · site-to-site VPN to on-prem DC
Security NSG-locked subnets · no public IPs · RBAC · TLS termination · webhook isolation
Automation Helm-based deploys · automated cert rotation
Repository Private — Enterprise Client Infrastructure

Designed and deployed a fully private Kubernetes cluster on Azure for an enterprise client, integrating with on-premises resources via Fortinet-managed VPN tunnels. Engineered selective public exposure for webhook endpoints while maintaining strict network isolation for all other workloads.

🏗️ Full-Stack Application Deployment — React + Spring Boot on Azure

End-to-end deployment infrastructure for a React frontend and Spring Boot backend connecting to an on-premises MSSQL database through Azure's hybrid networking stack.

Aspect Details
Stack · Ubuntu 24.04 LTS · Standard D4s v6
Networking Private subnet 10.3.2.x · Fortinet site-to-site VPN (AZ-DC-FG-vnet)
Security No public IP · SSH locked to Citrix static IP · 30-day backup · soft delete
Infra protectedsubnet · static private IP · NSG ingress rules
Repository Private — Client Deliverable

Built and documented the complete Azure infrastructure for a client-facing application, including VM provisioning, network security configuration, backup policies, and cross-site database connectivity through existing VPN infrastructure.

📦 Private Container Registry & Artifact Management

Nexus Repository-based private Docker registry with pull/push port separation, integrated into CI/CD pipelines for secure artifact management across environments.

Aspect Details
Stack + Nexus Repository OSS
Scale Centralized registry serving multiple deployment targets
Security Pull port 6001 / push separated · internal network only · authenticated
Automation Automated image builds and promotion via CI pipeline
Repository Private — Internal Tooling

Configured and maintained a Nexus-based private container registry as the central artifact store for all containerized applications, with strict port-based access control and CI/CD integration.
