Sidaarth (Sid) Sabhnani

I'm an incoming software engineer at IMC Trading in Chicago. I received my M.S. (2026) and B.S. (Honors, 2025) in computer science from the University of Texas at Austin, where I was advised by Prof. David Wu.

I'm primarily interested in systems performance — including in cryptography, operating systems, distributed systems, and ML inference.
