// about
Hi, I'm Mark.
I build software where the web meets the physical world: modern product interfaces, real-time systems, and building automation that people can actually enjoy using.
By day I commission building management systems at Africa Building Technologies. The rest of the time I build the software I wish those buildings came with.
