Hi, I'm

Sangit Manandhar

I use neovim and dvorak btw.

About

I'm a software engineer interested in how things work at the lowest levels. I spend my time working on programming languages, emulators, and systems infrastructure — the kind of software that other software is built on.

My work spans from implementing CPU emulators and parser generators in Rust, to designing functional languages in Haskell, to building production observability infrastructure with ClickHouse.

I believe that the proper way to understand a system is to build it from scratch.
