Hi, I'm David.
I've spent 20+ years working with technology.
I'm a contracting IT consultant, with a broad range of experience and skills. I'm an AWS Certified Solution Architect (Professional), a remote worker, I've written a book, and I blog on topics that interest me.
I'm interested in applying my skills (and curiosity) to short and long-term opportunities, both locally and remotely.
My most recent role was Senior Infrastructure Architect at Prophecy Networks Ltd in New Zealand, with a specific focus in networking, systems, open-source, IaaS, and business management.
A collection of projects created by David, and typically shared with the world.
Funky Penguin's Geek Cookbook ...is a collection of guides for establishing your own highly-available docker container cluster (swarm). This swarm enables you to run self-hosted services such as GitLab, Plex, NextCloud, etc..

Whenever possible, I like to contribute back to open source projects I come across. Sometimes my only contribution is a typo in a README, but as a maintainer of my own projects, I know that every little contribution boosts my motivation to keep working on the (volunteer) project!
I started dabbling in mining pools with Docker, and ended up maintaining a popular nodejs application, and a mini-empire of Kubernetes-driven mining pools!
I submitted a PR to the pfsense-packages team to simplify the way OpenVPN configs are exported
