Could you build this?
Partial Basic order book matching logic can easily be vibe-coded, but achieving genuine ultra-low latency, thread safety, and high-throughput memory layout in Java requires specialized systems tuning.
What it would actually take: A production version requires Java 21 with Project Loom or the LMAX Disruptor pattern, cache-friendly off-heap or zero-GC data structures, and deterministic lock-free data structures for the limit order book. Engineering this demands deep knowledge of JVM memory profiling, latency jitter reduction, and network I/O optimization.
