I am a Platform and DevOps Engineer specializing in Kubernetes, Declarative GitOps (Flux CD / ArgoCD), Terraform Infrastructure as Code, Bare-Metal Virtualization (Proxmox VE), Zero-Trust Networking, and Multi-Cloud Resilience.
🎓 Education: Master of Technology (M.Tech) in Renewable Energy Systems — National Institute of Technology (NIT) Kurukshetra
⚡ Philosophy: True infrastructure mastery comes from operating self-healing systems under real-world physical and networking constraints.
🌟 Featured Flagship: Homelab-Ops (Sovereign Cloud Platform)
A production-grade, self-healing sovereign cloud platform running on bare-metal Proxmox VE 8 and K3s in Mumbai, integrated with supporting cloud infrastructure in Oracle Cloud (OCI) and Google Cloud (GCP):
- 🔒 Zero-Trust Edge Ingress: Traverses residential Carrier-Grade NAT (CGNAT) using in-cluster Cloudflare Anycast Tunnels (
cloudflared) with <15ms latency and 0 open firewall ports. - 🔄 Deterministic GitOps Continuous Delivery: Complete fleet reconciliation managed via Flux CD v2 with strict dependency ordering (
appsdepends onplatform). - 🔑 In-Git Secret Cryptography: Declarative secret hydration using Mozilla SOPS + Age asymmetric encryption; decrypted strictly in-memory by Flux without plaintext on disk.
- 🐘 Stateful High Availability: Relational databases managed by the CloudNativePG Operator with continuous WAL archiving to S3 and self-healing automated failover.
- 💾 Dual-Tier Hardware Storage: NVMe flash partitioned for high-IOPS PostgreSQL engines and 1TB SATA mechanical disk dedicated to document indexing and media archives.
- 🛡️ Out-of-Band Multi-Cloud DR: Independent external Uptime Kuma heartbeats in OCI Mumbai and GCP; 3-2-1 backup compliance with offsite encrypted Restic backups.
