Rockstar🎓
Top SchoolIvan Ristović is a Senior Researcher with a decade of experience specializing in GraalVM Native Image, serverless runtimes, and JVM internals. At Oracle he has improved startup performance and runtime support for Espresso and Native Image, contributing low-level fixes and temporary workarounds to the high-profile graal/graal repository and helping drive class metadata pre-initialization for faster boot. He also teaches computer science courses at the University of Belgrade, bridging research and classroom practice across OOP, functional programming, and software verification. Based in Serbia with a master's in computer science, he combines deep systems-level expertise with practical engineering pragmatism—often tackling subtle build and class-loading issues that reveal themselves only under heavy native compilation.
