Jiří Holuša

Jiří started as a quality engineer passionate about performance. He worked on low-latency data grids at Red Hat (Infinispan) and later Hazelcast, where he switched to the dark side of product management. The desire to dig deep into technical trenches drove him to Azul Systems, where he currently serves as Senior Product Manager of Azul Platform Prime, a performance-focused Java Virtual Machine (JVM). That enables him to spend his day looking at JIT compiler activity, reasoning about assembly, and doing exactly what he loves.
