I'm a Member of Technical Stuff at Weco AI. I work on self-improving coding agents, especially their eval loops, harnesses, and context management. I built @Aiden, which we use to optimize open-source projects. In 2026, Aiden became the #1 contributor to OpenAI's Parameter Golf.
Before Weco, I built backend systems (trading) in Rust, Go, and Node.js at Hex Trust and worked on Hyperledger projects through The Linux Foundation.
My research took me through Nanyang Technological University, Zhejiang University, Hong Kong Baptist University, and Xi'an Jiaotong-Liverpool University. I studied Information and Computing Sciences at the University of Liverpool and XJTLU.
