CUHK (computer engineering) · Founder of directwire — a Rust organization building public-key-native networking for autonomous agents · Founder of NeuralZoo
I write high-performance infrastructure at the seams of protocols, agents, and money — transport that beats TCP, portable AI identity, institutional-finance codecs, ZK-enabled machine learning, and the settlement layer for machine commerce.
Public-key native networking for autonomous agents — dial by public key, not by IP.
| Repo | What it is |
|---|---|
| agent-transport | Message-oriented agent transport: single-packet round-trip, 8-level QoS, loss-resilient GRANT/SRPT scheduling over UDP. 5.2× lower P99 than TCP on short messages. |
| directwire | Rust workspace: p2p-mesh (iroh-style mesh) + gm-pq-stack (SM2 + ML-KEM-768 hybrid transport) |
| messaggero | A2A-compatible high-performance multi-agent transport: bincode fast path over Unix sockets + A2A HTTP |
| culmen | persona/v1 — a portable format for AI personas that remember, grow, and relate; runs on Claude Code · OpenClaw · Hermes · dsh |
| fixfast | High-performance Rust FIX/FAST reference implementation for institutional finance |
I deliberately place first bricks into young ecosystems — work that yields deterministic recognition and compounding value, regardless of any single project's fate.
