Hi, I'm Rohan — a systems engineer based in Los Angeles. I work on data systems internals at Massive, where I'm building Atlas — a financial markets database powered by Apache DataFusion. Day to day, that means working across the stack: query planning and optimization, incremental and continuous execution, and the storage and networking layers underneath.

Lately I've been deep in stream processing — extending DataFusion to handle unbounded data with correct, continuous execution. I talked about this recently at the DataFusion meetup in Stockholm.

I tend to pull on threads — if I'm using a system, I want to understand how it works. That curiosity drives most of what I share here.
