What we do?

Win microseconds. Control p99.9. Stay deterministic.

We design, audit, and rebuild high-performance trading infrastructure for teams competing at microsecond precision. Faster where it matters: the tail.

HFT systems fail because of jitter, queues, packet drops, recovery gaps, protocol edge cases, and observability blind spots. Tail latency decides winners.

  • Tail latency p99.9 kills PnL even when p50 looks great
  • Jitter from non-deterministic execution paths
  • Packet loss during volatility spikes
  • Microbursts overflow buffers and amplify latency
  • Feed gaps, replay inconsistency, broken recovery
  • Protocol complexity: ITCH, OUCH, FIX, native APIs, throttles
  • Risk vs latency: safety checks adding unpredictable delay
  • Missing visibility: no NIC to kernel to userspace breakdown

If you cannot measure it precisely, you cannot optimize it.
