about

I am Rut Vora, a software engineer interested in Systems and Networks, especially Systems and Networks Security.

I currently work at Arista Networks on the PCIe subsystem of their switches.

Before joining Arista, I was a Master’s student in Computer Science at the University of British Columbia, advised by Prof. Aastha Mehta.
My thesis is titled “Side channels in networks: from the internet to interconnects” and is available here.

I started my career in networks in the Office of the CTO at F5, Inc..
There, I created various proof-of-concepts for accelerating F5 products. My works spanned technologies like eBPF, DPDK, P4 and WASM. For details, you can check my resume.

I completed my undergraduate in Computer Science from BITS Pilani in India (2016-2020).
