My Portfolio Website

Implemented as a GitHub Page, you're looking at it!

Basic HTML, CSS and JavaScript.


Terrarium is a variation on Conway's Game Of Life, implemented as a Java console application.

Bitcoin & Lightning Network full node

I'm running a dedicated Xeon server from a spare room in my home as a full node supporting the Bitcoin network, and have recently added the Eclair implementation of the Lightning Network to it.

With its base template looking suspiciously like the one I used for this Portfolio page (never fix what is not broken ;) ), I created the website for Bake-and-Shake, which is a project by a nephew of mine.

Basic HTML, CSS and some copy-paste.
