Summary
Self-taught engineer and the sole IT for a 230-person manufacturing site — I built the company's entire tech backbone from two repurposed desktops: server infrastructure, networking, security, and in-house ERP software, using open-source and AI to ship reliable systems on a near-zero budget.

Sole IT · Infrastructure, DevOps & Development
Nov 2025 — Present
- Built the company's on-premise infrastructure from scratch on two repurposed desktops — a Proxmox VE + PBS cluster running 7+ virtualized services (NAS, reverse proxy, DNS, VPN, monitoring) with automated nightly backups and near-100% uptime.
- Redesigned the factory network for ~230 staff and 60+ devices: dual-WAN load-balancing + failover, a structured /24 IP plan, and WireGuard / Tailscale remote access.
- Cut recurring IT costs ~45,000฿/year by self-hosting open-source replacements (OpenMediaVault, Wazuh + Defender), and automated daily ops for 50 workstations with PowerShell + RMM into centralized dashboards.
