Yon

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.

CIDR Calculator & Subnet Planner

Fully 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.

RAID & ZFS Performance Calculator

Estimate 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.

I 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.
