AI Product BuilderQuant Researcher

Hi, I'm Lavine.

I have a background in Mathematics and Applied Mathematics and am currently pursuing an MSc in the Department of Computer Science at City University of Hong Kong. My work focuses on two connected tracks: AI products and quantitative systems.

I like turning ambitious ideas into working systems from zero to demo, connecting technical judgment with product context, growth thinking, and stakeholder communication.

Recently, I've been exploring AI agents, data-driven products, and interactive worlds that make complex concepts easier to use, explain, and share.

Selected Work / Updated 2026

Projects as evidence,
not just a list of ideas.

AI products, quantitative research, and interactive systems — each tied to a result, a working prototype, or a public artifact.

Current Builds / Quant systems in public

Cleaner research loops, with the evidence attached.

My current direction is to make quantitative research easier to inspect and reproduce: point-in-time inputs, explicit failure states, cost-aware validation, and public implementation notes.
