Infrastructure and fintech · Budapest, Hungary
Finance-trained, infrastructure-focused. I spent five years in finance — markets, risk, credit analysis — and now build and operate the systems underneath that kind of work. I would rather understand a stack end to end than only the layer I write code in.
- 📍 Based in Budapest. Residence and work permit in progress (Enter Hungary).
- 🗣️ English — fluent · Hungarian — A1–A2, actively learning.
- 🎯 Open to IT infrastructure, systems administration, security operations, and fintech roles — on-site, hybrid, or remote.
- 📚 Studying for CompTIA Security+ and CCNA.
A self-hosted homelab built on Proxmox VE — LXC containers and KVM virtual machines, Pi-hole handling network DNS and filtering, a Tailscale mesh with subnet routing for remote access, Docker services behind a reverse proxy, and Uptime Kuma watching all of it. Hardened with key-only SSH, a default-deny firewall, and UPS-triggered graceful shutdown.
That repository has the full architecture, the hardening checklist, and a runbook covering the failure modes I actually hit and how each was diagnosed.
