writeups

i write when something clicks or when i need to think out loud. side quests is where i dump running notes and experiments. i also went deep on npus and where they break, wrote about building my own curriculum as a freshman, and put out a thread on staying calibrated as a generalist in fast-paced environments.

also, my well curated spotify playlist.

projects

things i built, mostly in my first year of college. i tend to go deep on one idea until it either works or teaches me something.

• sameshi - ~1200 elo chess engine squeezed into 2kb of c, which hit the hn frontpage and was liked by andrej karpathy
• spheni - vector search built from scratch with product quantization and residual encoding, which was well received on r/developersIndia
• dunefetch - neofetch, but the ascii art is a live falling sand simulation, which was loved on r/unixporn

i also built path tracers, inference runtimes, quantization libraries, syscall tracers, gemm kernels, distraction blockers, and pixel editors - all on github. the most used by strangers on the internet is, unexpectedly, yars - a reddit scraper.
