Hi, I'm Jaime.

System Administrator with hands-on experience supporting people and technology across multiple office locations.

My work spans Microsoft 365, Active Directory, endpoint management, networking, backups, and security. I enjoy tracing difficult problems to their root cause and turning the fix into a reliable process my team can use again.

Outside of work, I build and maintain a home lab where I explore virtualization, storage, networking, and automation. It gives me room to test ideas, learn by doing, and bring what I learn back to the systems I support every day.

Featured IT Projects

Multi-Node High Availability Virtualization Cluster

Proxmox VE ZFS NFS / SMB LXC

Architected and built a dedicated three-node high-availability homelab cluster running Proxmox VE on compact enterprise thin clients to host core infrastructure services with automated failover.

  • Implemented localized ZFS storage pools paired with network-attached storage targets for redundant backup storage.
  • Configured automated guest backup routines and snapshot scheduling with minimal downtime.
  • Isolated infrastructure services into lightweight LXC containers, including centralized DNS sinkholing.

Centralized IT Alert & Monitoring Pipeline

Power BI Power Automate API Integration

Designed and deployed an automated reporting pipeline aggregating critical alerts and threat intelligence across multi-vendor IT management and endpoint protection platforms.

  • Parsed and routed alerting webhooks to eliminate manual daily console checks across disparate vendors.
  • Engineered centralized Power BI dashboards offering real-time visibility into infrastructure health and security events.

Secure Overlay Mesh Networking & DNS Architecture

Tailscale Pi-hole WireGuard DNS

Established a secure, zero-trust remote access architecture connecting remote endpoints, virtualization nodes, and internal storage arrays without port-forwarding on public IPv4.

  • Integrated local network-wide ad-blocking and domain resolution rules through a virtualized Pi-hole DNS sinkhole.
  • Enforced strict tunnel security policies and isolated administrative traffic across internal and external subnets.
