## **Technical Projects**

### **Kubernetes Infrastructure & Automation Platform**

**Lead Architect**

*Designed and deployed a production-ready K3s Kubernetes cluster managing 40+ microservices using GitOps principles.*

- **Automated Provisioning Pipeline:** Engineered a VM provisioning workflow using **Packer** to build immutable Fedora images and **govc** for on-demand node scaling on vSphere. Reduced node deployment time from hours to minutes by automating OS configuration and K3s bootstrapping.
- **GitOps Workflow:** Implemented **Flux CD** to synchronize cluster state with a Git repository, ensuring version control and automatic reconciliation for all workloads including Traefik, Cert-Manager, and database operators.
- **Observability Stack:** Deployed a full monitoring stack using **Prometheus** and **Grafana** with custom dashboards to track cluster health, resource usage, and automation job status.
- **Identity Management:** Integrated **Authentik** to provide Single Sign-On (SSO) and OAuth2 protection for all internal services, securing access via Traefik ingress middlewares.
- **Security & Secrets:** Enforced security best practices by implementing **Sealed Secrets** to encrypt sensitive credentials in the public repository and automated TLS certificate renewal via Cert-Manager and Cloudflare DNS.
