About
Abhinav Agarwal
Sr. Software Developer at Rubrik, working on high-throughput distributed filesystems in cloud environments. Previously optimized latency at high-frequency trading firms. MS in Computer Science from UW–Madison, B.Tech from IIT Kharagpur.
I build storage systems in C/C++ and spend my time thinking about Linux kernel internals, memory safety, io_uring, and FUSE. When I’m not writing filesystem code, I’m usually breaking it.
