Hi, I'm Vadzim Tuhuzbayeu

I work in performance engineering, focusing on how systems behave under load.

I’m less interested in single metrics or specific tools. What matters to me is how the whole system reacts to stress: where it breaks, how problems spread between components, and which architectural decisions really matter as systems grow more complex.

Over time, I stopped treating performance testing as a final step or a checklist. I care more about the decisions performance work supports – trade-offs, limits, and long-term system behavior.

I also run a production side project end to end. It allows me to test architectural assumptions using real traffic and to deal with the consequences of design decisions, not just theory.

This blog is a place where I write to clarify my thinking, document mistakes, and reflect on real system behavior. It’s not a collection of tutorials or tool comparisons.

Outside of work, I enjoy road trips, filter coffee, time with my family, and listening to music one album at a time.
