I am Javid Rzayev. I work on Linux systems performance and I write eBPF tools to see what the kernel is actually doing. I am not an expert, just someone who is learning. I believe that renting more cloud resources or buying a new host is not the right solution for performance issues. Instead, we should review host performance, improve how they work, and fix the apps or components that create these issues :).

Most of what I publish starts in my GitHub Account

Lately I have been exploring the edges: eBPF + Kubernetes observability, and eBPF around TPU/NPU accelerators - how much of an ML accelerator’s behavior you can actually see from the kernel, and where the vendor drivers stop you. The single purpose of all this is learning and sharing interesting topics and findings with you.

Get in touch

If you use one of my tools and hit a bug or have an idea, the fastest path is a GitHub issue on the relevant repo. Of course, you are welcome to be a contributor (just create a PR) in any repository or tool that you find in my GitHub account.

I also like to play chess. If you want, find me on Lichess and send me a challenge :).
