big projects:

1. spheni: vector search library with product quantization and residual encoding
2. rayfloat: a multithreaded, bvh accelerated cpu path tracer
3. sarvam.c: an inference runtime for sarvam-1 model, with support for sentence-piece tokenizer

small projects:

1. sameshi: a ~1200 elo chess engine that fits within 2kb of c
2. dunefetch: if neofetch and a falling sand simulator had a baby
3. lookin: a dead simple linux syscall tracer
4. frogemm: a small gemm library in c to do fast matmul
5. inwhale: a quantization library made from scratch

very old projects:

1. grudgepixel: a pixel art editor with animation support (made it when i was 14, with c/raylib)
2. amine: distraction blocker but it actually takes control of your hardware
3. yars: reddit scraper without api keys and all
4. touchgrass: a chess engine playground in python
5. froginfer: an inference runtime for llama2 models in c
