I've coded a fair bit of things over the time, both as individual projects, and occasionally on coding challenge websites (e.g. CodinGame). Here's a list of projects I've wished to in particular showcase.
Please note many of these are a bit on the older side; I cannot in general showcase stuff I do at work, as it is developed solely for the customers - and hence it is their prerogative to decide on publicity
A collaborative software project developed for the University of Jyväskylä, for course TIES405
To-be Elixir password strength library
Fingerprinting audio recognizer
Second version of Konsensus, rewritten in Go
A working prototype (and evolution) of a MC map renderer in Go
HDD content statistics tool
Primitive (and obsolete) Ruby MC admin console
First version of Konsensus, the site generator powering the site
Current version of Konsensus, again in Ruby
A toy programming language written in Rust
A shit-y (per name) card game in TS
