Projects & Demos

• ROTARTSI82/Scacus: A UCI chess engine written in C++, with magic bitboards and multithreading. Supports both normal chess and the anti-chess variant, rated at about ~1600 Lichess ELO in chess.
• ROTARTSI82/ATCS
  • ATCompilers: A compiler for a custom Pascal dialect targeting MIPS32 assembly, written in Java.
  • LLM: Trained a custom 40M-parameter character-level transformer on my text messages. The transformer was implemented from scratch in PyTorch, and I performed a scaled-up training run of a 150M-parameter model on UW's Hyak Klone supercomputer cluster.
  • ATNeural: A toy neural network for digit recognition written in Rust, implementing backprop and the ADAM optimizer.
• WebGL Ray Tracer with GLSL (extremely janky)
• 4-Bit Breadboard Computer
