About Me
Hey, I'm Yash
Backend Developer · Distributed Systems · HFT Specialist
I build software that handles serious scale — trading engines, distributed pipelines, real-time infrastructure. I care deeply about performance, correctness, and clean architecture. When I'm not profiling Go binaries, I'm in the gym or grinding algorithms.
