Not a catalogue of services — a record of how I build resilient systems, teach what I build, and keep it practical with open tools.
🧩 This Website (NGINX, TLS, GPG, 3D)
Self-hosted, hardened, and documented. Clean headers, zero trackers, GPG-secured contact, and live 3D model hosting — the infrastructure itself is part of the portfolio.
Outputs: runbooks, checklists, and durable muscle memory
🖧 Proxmox Homelab Cluster
Old laptops, disciplined ops: scripted health checks, weekly inventories, and live migration practice. A small cluster that behaves like a serious one.
Teaching VMs for Linux, compliance, and troubleshooting
Failures treated as data — recovery rehearsed, not improvised
🛰️ Drone Mapping & Orthophotos
Drone flight plans processed with WebODM. Accurate orthos and 3D meshes for agriculture, land use, and property showcase.
Inspired by licensed software where I didn't want to spend $300 a month, this is what FOSS does
Presets that balance quality, workflows, and hardware limits
One step at a time, terminal feedback first, no silent leaps. Chats become living checklists, recovery prompts, and scripts I can reuse.
Structure the noise, use the assistant: info → command → confirm → next
Artifacts, not fluff: configs, playbooks and AI implementation that is dependable

Server racks, cabling, wireless bridging, failover logic
Conference and signage systems in real-world use
Always delivered fully documented and stress-tested
🙌 I Train for Free — If the Idea’s Worth It
If you're building something real and private — something that makes sense and isn't just for show — you can count on my help. No invoices. No catch.
Every project is documented, testable, and designed to run without me. That’s the goal.
