Marco Sussitz is an engineer at Dynatrace who works at the boundary of Java and C++. He writes JVMTI agents, instruments bytecode, and digs into JIT, memory, and thread behavior. You’ll often find him sorting out class loaders or reading the spec longer than he should. Before Dynatrace, he worked on cloud video encoding with FFmpeg. In his off hours, he’s bouldering or in the mountains.
