About the author

Hi there!
My name is Roman Kashitsyn. I'm a software engineer at dfinity, where I have been working on orthogonal persistence, state snapshotting, state certification, state sync protocol, message routing, and much more. I have also co-authored a few relatively popular canisters: registry, ledger, internet identity backend, and certified assets canister.
Before dfinity, I worked on large-scale distributed systems at Google.Shopping and Yandex.Maps.

What does "mmap" mean?
"Mmap" stands for memory-mapped file I/O. This ancient technology is a beam of light in the murk of the modern technological world darkened by unnecessary complexity and layers of abstractions. I like mmap so much that I called my blog after it.
