Featured Work

Best signal

1) Parallel ZK Playground (Monad Testnet)

Batch verification demo — storage layout for parallel execution, no write hot-spots. Batch verify 10 / 50 / 100 proofs per tx; metrics dashboard (gas, latency, success rate).

Solidity 0.8.24 · Hardhat · Next.js 14 · ethers v6 · Tailwind · PNPM monorepo

→ zkhahaha

2) LLM Werewolf Arena (DeepSeek)

Multi-agent simulation — system prompts, personas, private memory isolation. Single API, multi-role agents; voting / night actions pipeline.

Agent orchestration · prompt protocols · state management

Engineering + research, not vibes

AreaFocus
Research / ModelingRegime awareness, indicator diagnostics, signal design with leakage awareness
BacktestingCrypto pipelines (Binance), MAE/MFE, win-rate vs tail-risk, stop-loss sensitivity
ExecutionBot-driven workflow on Linux/VPS, Docker, reproducible runs
Risk / ProcessPosition sizing, failure-mode thinking, robustness over “perfect params”

Looking for

Roles in Web3 engineering (protocol / infra / tooling), AI agent applications (orchestration, state, productization), Quant dev / data pipelines (research → backtest → execution).

Teams that value clean code, measurable iteration, and systems thinking.
