I'm a researcher and engineer who thinks best when building. My PhD covers evolutionary computation, artificial life, and procedural content generation, but the same instinct drives my game projects and hardware builds: I'm drawn to designing systems that generate, evolve, and surprise, and that can actually solve problems. I'm looking for work where research and making are the same thing.

Projects

• Pixel Breeder
  -- non4to/PixelBreeder
  Interactive evolution tool inspired by Picbreeder, built for PICO-8. It generates patterns from mathematical functions, allowing users to "breed" complex patterns through selection and mutation. A demonstration of emergent visual complexity from simple genetic rules.

• SoftbodyGodot
  -- /non4to/SoftbodyGodot
  Artificial Life simulation of softbody organisms that self-replicate, form physical attachments, and evolve behavior over time. Each organism carries a gene encoding movement, attachment, and survival strategies. Built in Godot 4 with Rapier2D.

• fGBA - The pico8 game console
  -- click for details! A retro handheld console built from scratch inside a Game Boy Advance shell. Powered by a Raspberry Pi Zero 2W, with a custom SPI display pipeline (ILI9341V + fbcp-ili9341), GPIO button input, PAM8302A audio amplifier, 2000mAh battery with boost converter and charger module. Running RetroPie, PICO-8 and steam link.

  fGBA: PICO-8 running on ILI9341V display.

• RGPlants - PROCJAM2024
  -- /non4to/PROCJAM-2024
  Open-ended evolution simulation where 4,096 color-coded organisms spread, blend, and mutate across a grid. No fitness function — only emergent patterns from local neighbor interactions. Built with Python and Pygame. Submitted to PROCJAM 2024.

• YASOULS (Yet Another Soulslike) - (in progress)
  -- /non4to/YASOULS
  The Soulslike in the name is mostly because I loved the parry mechanic in From Software's Sekiro:Shadows die twice. I got inspired! I didn't want to make a 3D though, I also really like beat'em ups. So YASOULs is born! Another motivation to start this project was that I really want to be able to play in fGBA.

  YASOULS is an action-oriented game focusing on parry mechanics, modular behavior for enemies, and a planned evolutionary AI backend.

• Small games and interactive demos.
