hey, i'm sarthak. 20 y/o cs undergrad into inference systems, high-performance computing, and distributed systems.

mostly obsessed with the machinery behind intelligence: how a pile of matmuls turns into useful behaviour, how agent harnesses turn that behaviour into useful work, and how to make the systems around it fast, reliable, and efficient.

can work across any stack, but most proficient in ai systems, infra, and post-training.

this site is a log of things i'm learning, building, or overthinking. usually the latter.
