Welcome to my little corner of the Internet. This is where I document my journey through networking, Linux, Docker, DNS, Cloudflare, virtualisation and home infrastructure.
01 / About
Always learning. Always building.
I'm a telecommunications and voice engineer with a strong interest in networking, infrastructure and technology. My homelab gives me a place to experiment, break things, understand why they broke, and build them again.
02 / Technology
Technologies I'm exploring.
A mixture of technologies from my professional networking background and the systems I'm learning through my homelab.
CTR
Docker
Building containerised services and learning images, volumes, networks and Docker Compose.
DNS
DNS
Exploring DNS resolution, A records, CNAMEs, MX records, recursive queries, local DNS and split-horizon DNS.
CF
Cloudflare
Using my personal domain to learn public DNS, Workers, TLS and secure ways of connecting services.
VM
Proxmox
Running my virtualisation environment and experimenting with virtual machines, storage and networking.
NET
Networking
Applying networking fundamentals across routing, DNS, TCP/IP, SIP and home infrastructure.
03 / My Homelab
The lab behind the learning.
A compact environment for learning infrastructure, virtualisation, containers, networking and private cloud services.
Lenovo ThinkStation P330 Tiny
Proxmox VE
Docker
Portainer
Immich
Pi-hole (Planned)
More to come...
04 / Currently Learning
The journey continues.
Linux Administration
Commands, networking, services,
logs and troubleshooting.
Docker & Containers
Compose, networking, persistent
storage and container management.
DNS
Pi-hole, local DNS, Cloudflare,
dig, DNS records and eventually BIND9.
Security
TLS certificates, secure remote access,
firewalls and network segmentation.

05 / Contact
Let's connect.
Interested in networking, telecommunications, Linux, DNS or homelab technology? Feel free to get in touch.
Say hello.
This site is primarily my personal technology playground, where I document what I'm learning and experimenting with. I'm always interested in connecting with others who enjoy technology, networking and home infrastructure.
