Capture the Flag competition for Hack The Midlands 4.0 and 5.0.

I developed and ran a 8-challenge mini-event for the hackathon, involving chatbots, dns servers, reverse-engineering and more!

An entirely open-source port forwarding helper from localhost built using SSH tunnels.

I built it out of a frustration that none of the existing tools in the area were open source or had minimal client-side dependencies.

Timetable extractor and converter for University of Birmingham web timetables.

The default university timetable interface was complex to navigate, so I constructed a command line tool to extract it into a variety of formats.

I enjoy tinkering with a number of technical projects at home whenever I have a few spare moments. I’m also attempting to branch into blogging more regularly, producing technical content and tutorials for both beginners and experienced developers.
I love playing games, from a variety of board and card games with a group of friends, all the way to single-player games on my computer at home (I do love a good roguelike).
I’m always up for trying new food, and regularly try and find new places to eat out wherever I am. I also really enjoy cooking at home for fun!
