Backend and distributed-systems engineer. I build Go-based blockchain infrastructure — the layer where a bug can cost real money and a bad block cannot be rolled back.
| Project | What it is | My part |
|---|---|---|
| chain33 | Open-source modular blockchain framework; public mainnet since 2018 | Core maintainer since 2018 — 1,060 commits |
| plugin | The framework's plugin ecosystem: consensus, dapps, cross-chain, L2 | Core maintainer — 509 commits |
- P2P networking — pluggable transport and sub-protocol layers, gossip broadcast with deduplication, DHT peer discovery, DoS protection driven by validation feedback
- Consensus and finality — Snowman/Avalanche adapter, fork preference, out-of-order block acceptance
- Cross-chain and custody — three-layer bridge design (TSS threshold custody, on-chain proof verification, asset state mapping); BTC and other Bitcoin-native assets
- Storage, state, and compatibility — persistent state machines, LevelDB/Badger storage, EVM address and precision mapping, Bitcoin Script, M-of-N and CSV (CheckSequenceVerify) account templates
- Performance and reliability — pprof and GC tuning, end-to-end benchmarking, concurrency and consistency debugging
I define boundaries, failure modes, and acceptance criteria before implementation, and keep verification independent of the author. I use AI heavily for implementation, review what ships, and own the design and the correctness call. Stacks I've shipped in: Go, C/C++, Rust — across embedded, backend, and blockchain systems.
