Technical Focus

Systems Engineer specializing in enterprise datacenter infrastructure and Tier 4 infrastructure escalations. I have comprehensive hands-on experience handling almost all major virtual infrastructure (VI) technologies—including VMware ESXi, Hyper-V, and Proxmox—along with the core routing, switching, and firewall networking required to sustain them. My background includes configuring and managing enterprise storage infrastructure (SAN/NAS stacks) across multiple block and file protocols, deploying automated backup layers, and maintaining active multi-site replication layouts.

Enterprise Infrastructure

  • Virtual Infrastructure Allocation Full administrative ownership over client and corporate production virtual architectures (VI) and core enterprise environments.
  • Disaster Recovery Integration Designing, maintaining, and validating complex backup policies, synchronous file systems replication, and automated failover orchestration to primary DR nodes.
  • Advanced Incident Demarcation Serving as the supreme technical escalation boundary to diagnose root-cause faults, optimize client topology, and permanently eliminate systemic anomalies.

The Homelab Cluster

  • Bare-Metal Engineering Sandbox Designing and independently maintaining a robust, non-homogeneous compute cluster built to exact corporate environment standards.
  • Secure Autonomous Mail Routing Deploying self-hosted mail infrastructure using Mailcow stacks, implementing strict relaxed canonicalization parameters to enforce valid cryptographic signatures.
  • Programmable Edge Networking Utilizing automated infrastructure hooks via Cloudflare to implement resilient proxy mechanisms, real-time edge filtering, and secure origin protection.
