Why We Choose Rust for Fintech Infrastructure

When Meridian Capital needed to process 50,000 orders per second with sub-10ms latency, Java wasn't going to cut it. GC pauses alone could cost milliseconds — unacceptable in trading.

Rust gives us C++-level performance with compile-time memory safety. No null pointer exceptions in production. No data races. The borrow checker catches concurrency bugs before they ship.

The migration took 4 months. The result: 81% latency reduction and zero memory-related incidents in 12 months of production.
