# Szymon Kulec
Lead Developer Advocate at RavenDB pushing .NET runtimes to their absolute limits.

## About

Szymon Kulec builds fast data systems and advocates for architectural simplicity. At RavenDB, he focuses on squeezing maximum performance out of both engineering teams and the product itself.

His talks draw from real-world systems programming, often exploring what happens when you push the .NET runtime to its absolute limits. He covers everything from memory games and vectorization to surviving the sharp edges of the ecosystem.

He has one simple rule: he doesn't allocate before evening.
