Notes
- Software Engineer at Windsurf (Mountain View) Jun-Aug 2025, the summer Google hired Windsurf's founders and Cognition acquired the rest of the company (July 2025). He was there during the handover, which is how he came to Cognition; his public LinkedIn still lists the role as a Windsurf internship.Jun 2025
- Core Engineer and Researcher on Mantis at the MIT Computational Biology Group (Manolis Kellis's lab) since Jun 2024. Mantis uses LLMs to ingest and embed unstructured datasets and shows the latent space as an interactive map; it had about 50 beta users. He also led an engineering sub-team on data-science toolset integration and worked on retrieval-augmented agents with chain-of-thought.Jun 2024
- IOI for Macao: 2022 bronze (251.5/600, rank 94) and 2023 bronze (209.5/600, rank 107). His 2023 Macau IOI teammates were Chi Ho Zheng, Io Fai Lei and Pok Hong Lam.Sep 2023
- IMO for Macau three years running: 2021 honourable mention (8 pts, rank 348), 2022 bronze (28 pts, rank 146), 2023 silver (25 pts, rank 137/618).Jul 2023
- Medalled at both the IMO and the IOI in 2022 and 2023, which is rare for a small delegation like Macau's.2023

- Summer 2024 UROP with the MIT Computational Design and Fabrication Group under Prof. Wojciech Matusik, supervised by Michael Sun. He researched formal graph methods for training models on scarce data and built a dataset for industrial PLC code optimization with a Fortune-500 partner (GitHub repo jophy-ye/PLC-project).Jun 2024
- A June 2025 post by Manolis Kellis promoted a July 6 Athens AI hackathon run with SundAI Club, presented Mantis ('WhatIsMantis') as a cognitive workbench, and named the Mantis team.Jun 25, 2025
- Named in the Putnam Competition winners announcements for 2023 and 2025 (the 2023 announcement also notes MIT's first-place team).2025
- IMO Macau teammates: in 2022 Cheng In Cheung, Wang Iok Lin, Kuok Wai U, Chi Pang Lao and Siyang Lin; in 2023 Wai Chong Chan, Wang Iok Lin, Kuok Wai U, Chong Un Un, Ngou Hin Cheang and Song Pok Hong (per extraction from imo-official Macau results).Jul 2023
- MIT, Bachelor's in Mathematics and Computer Science (double major), 2022-2026.2022
Experience
Core Engineer, Researcher @ Mantis, MIT Computational Biology Group at Massachusetts Institute of Technology
Jun 2024 - Present
Cambridge, Massachusetts, United States
- Co-build Mantis which ingest & embed unstructured dataset with LLM, and visualise the latent space on an interactive map, to empower responsive interpretation of high-dimensional data, currently with 50 beta users. - Integrate retrieval-augmented agents with chain-of-thought analysis to enhance LLM’s reasoning capabilities. - Lead engineering sub-team on data science toolset integration and reviewed code to minimise adaptation cost.
Undergraduate Researcher @ MIT Computational Design and Fabrication Group at Massachusetts Institute of Technology
Jun 2024 - Sep 2024
Cambridge, Massachusetts, United States
- Researched on formal graph methods to optimize model training in domains with scarce data. - Composed dataset to apply the method to industrial PLC code optimization, collaborating with fortune-500 firm.
