• Deep understanding of Java core internals, multithreading, memory models, and garbage collection.
• Proven experience in GC-free or low-GC programming, including use of sun.misc.Unsafe, direct buffers, and memory-mapped files.
• Familiarity with Aeron, SBE, or other low-latency messaging libraries.
• Strong grasp of event-driven architecture and experience designing fully deterministic systems.
• Solid knowledge of time-series and analytical databases like ClickHouse; exposure to kdb+ or InfluxDB is a plus.
