I built an open-source Order Matching Engine from scratch to understand how real exchanges work

My main goals were:

Learn how real-world matching systems work
Study low-latency design tradeoffs
Build something useful for other devs learning system design

I’d genuinely love feedback on:

Architecture decisions
Performance bottlenecks
What features would make this more production-ready
