// About

Hey, I'm Aditya.

I write about the things that live beneath the abstractions — processor pipelines, memory hierarchies, compiler behaviors, and the hardware-software boundary where real engineering happens.

Right now I'm building LLM-powered agents at Synopsys R&D that automate hardware verification — and writing about what that actually looks like from the inside.

ErrBits is a place to debug assumptions and understand how machines truly work, one bit at a time.
