infrastructure · automation · things that mostly work

Background in payroll operations — the kind where the regulatory complexity is the interesting part and nobody wants you to fix it. So I started fixing it anyway, first with spreadsheets, then with Python, then with a homelab that grew until it needed its own router.

Currently based in the Netherlands. Building infrastructure and an AI agent simultaneously, which is either efficient or inadvisable. Possibly both.

Prowler in development

A modular AI agent built on Ollama. Capabilities live in modules, each governed by an SOP markdown file — ordered tasks, tools, error handling. The layer 2 model reads the SOP and executes. First serious module: payroll processing with Hungarian regulatory logic.

Banana Network running

Self-hosted home infrastructure on a BananaPi R4 router and Minisforum mini PC. WireGuard tunnels, Proxmox, Jellyfin, Nginx reverse proxy on a Hetzner VPS. Fits in a bag. Mostly stable.

Attendance Entry App deployed

Access-based attendance tracking system for 250+ employees. Automated validation and import/export, cut processing time in half. Built at a previous employer, still in use.

The full story — how the lab grew, how Prowler actually works, and why this started with a phone that still hasn't been flashed — is on the other side.
