Smart contract · age 11
2021
I wrote my first smart contract at 11, making me the world's youngest NFT programmer. CryptoTigers is an on-chain generative NFT collection; I gave half the proceeds to Crossroads Foundation's computer-refurbishment program, and still volunteer there monthly.

Live · kalinga.hk
A live multilingual PWA that helps Hong Kong's ~340,000 migrant domestic workers catch exploitation in their employment contracts. Photograph a contract, get a plain-language risk read in your own language, checked against HK statutory standards. Built safe by design: the AI reads and translates, but a deterministic rules engine computes the legal risk, so a model hallucination can never hand a vulnerable person wrong advice. A React PWA on Supabase (row-level security), Twilio, and Cloudflare.
Founder
since 2023
Launched and legally registered an e-commerce business at age 12, selling consumer tech across Hong Kong, the US, and the UK. Ran it end to end, from sourcing and the storefront to cross-border logistics, with a slice of proceeds going to reforestation in Madagascar.
Quantitative research · Dragon Prep
May 2026
An independent study mapping the Digital SAT's hidden adaptive scoring. I ran 80+ controlled experiments to reverse-engineer an IRT system whose parameters aren't public, then built regression models that predict section scores within R² > 0.97. Shipped as a 23-page paper, an interactive dashboard, and a stakeholder deck.
In development
A focused SAT prep platform with a question database, spaced-repetition flashcards, and a score calculator. Built for serious practice.
