Link: Puzzle Helper
As of early 2022 (the last time I checked) this is the best automatic 3D jigsaw puzzle edge pairing solution. Large scale python project that was originally intended to fully solve jigsaw puzzles to completion had to be cut short due to time constraints. Fortunately the work completed was the most integral part, edge pairing. It took around 1-2 years of coding, research, maths and problem solving. The documentation provided in the link above was my best attempt at summarising over 400 pages of notes, calculations and diagrams.
Link: Memories web app
An entry-level web app for users to create and share memories with each other. I wanted to learn some Java so I chose to do a project with spring boot backend and angular frontend. All of the technologies except javascript and html were new to me.
