About
Swarnim Arun
Systems, tooling, and the occasional long detour into how things actually work underneath.
I write about programming, systems, performance, and the tools I use. Most of what lands here started as a note to myself while building or debugging something.
I like working with Rust, F#, Zig, C++, TypeScript, Kotlin, C#, and Swift. I'm editor agnostic, but I like Helix and Zed.
