The best thing I've ever done is scale a real time leaderboard to 150,000 concurrent SSE connections on a single Linux machine, and I'm trying to improve on that still - https://github.com/pranshu-raj-211/leaderboard

Looking for internships or early full time roles, preferably with backend engineering oriented scope.

I write a bit on my blog, which I post here sometimes- https://blog.pranshu-raj.in

For context, this system was built in Go, Docker being used both by the server and client components. All the testing was done on a laptop running Fedora Linux.

I'd love to learn how this can be taken further, especially how to handle request spikes and reducing memory usage.

I built a real time leaderboard that uses SSE (Server Sent Events) as the main access pattern. When I tried to scale it I hit a limit of 28232 connections, with resource usage being nominal.

This was very peculiar, and the post describes my journey figuring out the cause of the issue and how I went past that limit, eventually scaling to 150k connections on a single machine (and my ideas on how to take this further, as I hit memory limits at this point).

I'm working on building an LSM tree db in Go, to learn more about the language and improve my understanding of db internals.

Also planned to try out some io_uring based disk operation eventually, as an experiment to learn more of the underlying OS stuff.

Can you give examples of which games have implemented this (if open source) for reference?

Hi, author of above blog here.

Thanks for posting, I'm glad you found this interesting.

Would be glad to know any feedback or requests you have, to improve further.
