I'm a master's student in Computer Science at the University of Hong Kong, currently interning at Ant Group on AI for quantitative research. I build agents that turn existing factors into trading strategies and backtest them, and I'm exploring how they can use backtesting feedback to discover new factors. Previously, I worked on agent evaluation, harnesses, and full-duplex multimodal interaction at Cybopal, and interned at Kuaishou.
 A CLI for paired A/B tests of Skills, rules files, and MCP setups. Measures task quality, trigger behavior, and token cost, with replayable records and evaluation budgets. Available on npm. |
 A testbed for stateful Chinese tool use, with state simulation, fault injection, and final-state and trajectory grading. Studies post-training and closed-loop execution through small-model proposals, validation, and planner fallback. |
