hi, i'm pustak.
21, cs undergrad at shiv nadar university. i like computer graphics, HPC, vidya, and shipping small weird software that occasionally works. find me as @pustak or @pustakalt almost anywhere.
(it's an LLM in a trenchcoat. be nice.)
# about
i'm 21 (as of feb 2026), currently doing my B.Tech in CSE at shiv nadar university (2023–2027). most of my brain is split between computer graphics, high-performance computing, and whatever rabbit hole i fell into last week.
outside of code: music enjoyer, general videogame goblin, occasionally writes things on blog.pustak.fun.
