HKEX OMD-C Low-Latency Fabric — Greenfield, Open Source

Production-grade UDP multicast fabric for HKEX OMD-C 239.1.1.1:5000. Built with C++20 concepts, SPSC lock-free ring, AF_XDP socket, cache-line padding. Open source for reviewable, extensible desk-specific alphas — validates at p99 0.40us on commodity Latitude 7480, 10× faster than typical 5us HFT target. MSA-ready with audit logs, runbooks, deterministic replay, MIT licensed.

HK-ClaimSentry 500K/sec — Real-time claims fraud & duplicate detection

Regex + embeddings hybrid pipeline with ONNX inference, RocksDB dedup store, Kafka streaming, and SFC Type 9 MSA audit trail. p99 < 8ms at 500K claims/sec. Designed for HK insurers requiring explainable fraud rules + ML hybrid with deterministic replay, runbooks, and on-prem/VPC deploy. Open source, MIT, production-hardened for market open survival.

FIX 4.4 Equities — QuickFIX p99 Fix, Zero-Copy, Ubuntu 24.04 CLI

Problem: QuickFIX/J is tool allocating std::string per field → 200-500us p99 breaks sub-2ms SLO for AAPL/MSFT/HSBA.HK.
Solution: C++20 zero-copy — buffer IS FixBuilder.build() = recv(fd,buf) wire buffer. FieldView {tag, string_view} slices original buffer, fields_[128] stack, linear scan '=' & SOH 0x01, auto 9= & 10=. Latitude 7480 validated, pedantic clean, e6384a7.

HFT Straddle — Volatility surface & gamma scalping

Sub-ms order book reconstruction, IV surface arbitrage, real-time gamma calculation with lock-free queues and kernel bypass. < 1.2ms p99 tick-to-signal. Built for prop desks & family offices running volatility arbitrage with FPGA-ready hooks, zero-deps deploy, and deterministic replay. Open source, MIT, C++17 to C++20/23, cache-aware, NUMA-aware.
