Hey. I’m Saksham Arora, a data scientist and quant researcher. I build things where the interesting constraint is the data, not the framework. Most of my work starts as a weird idea (“what if a live exchange ran inside a GitHub README?”) and turns into something I can measure. You can learn more about me through my portfolio (psst: press ` there).
I compete in quant trading competitions, build ML pipelines, and have a systems engineering background in low-latency C++20.
