Bits&Bricks

Network engineer · CCIE #70573 · Switzerland

I build networks, and the software that runs on them.

I'm Mike Keller, a network engineer and CCIE from Switzerland. Bits & Bricks is where my side projects live: software for clubs, tools for homelabs, and the lab underneath.

Hubra

U1 · app · hubra.club

Club software for Swiss clubs that looks good, has the features I wanted, and is priced so that even small clubs can afford it. It started for VollBuild, our makerspace club. Not open to other clubs yet.

Labdex

U2 · tool · homelab inventory

A small inventory for homelabs, because NetBox is steep and heavy for a lab. Describe the lab once and Labdex generates DNS, firewall aliases and an Ansible inventory. One container, SQLite, under 100 MB of RAM. I use it in my own lab.

Homelab

U3 · infra · the lab

Not just a lab: it's also my home network. OPNsense, Proxmox, a Synology and self-built servers, with Kubernetes, Docker and plenty of open-source homelab apps on top. Cisco Modeling Labs is where I practise, test and train for the CCIE.

My own AS

One day I want to run my own autonomous system: my own ASN, my own IP space, and BGP sessions with real peers. If you can help with transit, IP space or hosting, get in touch.
