Jmaa

Hello, my name is Jon. I make software, sometimes games, sometimes professionally.

My software work is split in three:

• Personal Hobby Programming
• Semi-professional Game Development
• Professional Work. Main skill areas are:
  • Programming language theory and implementation.
  • Secure Multi-Party Computation.
  • Blockchain and smart contract technologies.

Hobby Programming

I am a prolific hobby programmer, writing mainly in Python and Lua on my personal projects. See my public repositories for a subset of my work.

My hobby projects are pretty scattershot, including silly one-offs, convenience programs that took more time to develop than they save me and investment management systems.

One of my personal concerns is how individuals should have access to the data they are automatically producing every day, so they can use it for self-improvement. This project includes:

• The Personal Data API and scraper system, which allows the user to generate CSV files automatically from certain sources
• The (slightly misnamed) Git Time Tracker, which allows the user to take those CSV files and get CLI summaries, or export as iCalendar. Also allows you to see an estimate of how much time you spent working in git repositories.
• Components of the aforementioned investment system, such as fin-depo, which can automatically download asset portfolios from various crypto exchanges and banks.

Game Development

I am a semi-professional game developer, developing games with some friends under the Takunomi label. We have one early access game, and several game jam prototypes, due to participating in 5 Nordic Game Jams throughout the years. I mostly use LÖVE for my game engine needs, and even built my own 3D engine on top of LÖVE.

Full Games:

• The Girl Who Kicked a Rabbit (2024?): Early access game. In development since 2016.

Game jam releases:

• Home Dungeon (2024): Tactics Idler. For Nordic Game Jam 2024. Fifth use of my 3D engine.
• Rabbit Knight (2023): JRPG. Solo project. Won 'Voyager' award at K-Jam 2023. Fourth use of my 3D engine.
• Sasuga Keisatsu (2023): A top-down shooter, where the enemies are Japanese snack foods. for Nordic Game Jam 2023. Third use of my 3D engine.
• The Rabbit Age (2022): Tetris/Puyu-puyu-like. For Nordic Game Jam 2022. Second use of my 3D engine.
• Nijousatsujinjikenriron (2018): Talking simulator. Esoteric murder-mystery in an elevator. For Nordic Game Jam 2018. First use of my 3D engine.
• Doki Doki Densha Sekai (2016): A relaxing simulation of Japanese subways. Nominated for 'best game' at Nordic Game Jam 2016.
