Technical Lead • Systems Engineer
I design, automate and maintain reliable IT infrastructure as Technical Lead for a small team — primarily Windows Server, Active Directory, Group Policy and Cisco networking across education environments. Heavy PowerShell user who loves clean, idempotent automation that doesn't wake me up at 3am. Linux and Go fill in the gaps when needed.
Core Stack
Projects & Tools
Interactive, fully client-side editor for Chrome's ManagedBookmarks policy. Build complex nested bookmark structures, import existing JSON, and export ready-to-deploy policies for GPO or Intune. Perfect for school districts and locked-down environments.
Launch EditorEditor for Chrome ExtensionSettings policies (force_installed, update URLs, blocked, etc.). Supports Extension ID entries, Update URL rules, and the Default (*) catch-all. Essential companion tool for managed browser fleets.
Launch EditorInteractive curriculum platform built to help System Administrators deeply understand the technologies they administer. Curated episodes across Networking, Security, Cryptography, and Hardware with timestamped curator notes, progress tracking, and a robust background audio player. Fully self-contained PWA. Under active development.
Launch CurriculumFully client-side IPv4 toolkit. Calculate any CIDR block (network, broadcast, mask, host range) with a clickable bit grid, then visually carve the block into subnets — divide and join with a click. Tag each subnet with a VLAN ID, name, gateway, and notes, then export ready-to-paste Cisco IOS config, CSV, or JSON. The entire plan is encoded in the URL, so a single link rebuilds the whole layout.
Launch ToolkitEstimate real-world IOPS and throughput for HDD/SSD arrays across RAID 0/1/5/6/10/50/60, ZFS RAIDZ1/2/3, and striped mirrors. Models your workload mix, block and stripe size, controller cache, and parity write penalties, with a four-corner capability readout (random/sequential read/write) plus capacity and fault tolerance. Includes a live controller-cache simulation showing burst absorption, latency, and queue depth — with a battery-failure mode.
Launch CalculatorI also build and maintain custom PowerShell tooling for AD user/group automation, GPO deployment, device imaging, and various embedded/RP2040 projects. Let me know if any of these would be useful to you.
