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 in Rust, Go, and Node.js at Hex Trust and worked on Hyperledger projects through The Linux Foundation. I was also in the first cohort of Network School with @balajis.
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.
