I build quiet software with a point of view.

Most software asks to be noticed. I’m interested in the opposite: interfaces that leave room to think, systems whose structure stays legible as they grow, and details whose charm comes from how they work.
Open to frontend and full-stack internships in Sydney.
Oasis — a digital garden that behaves like a place
Oasis is where I write, listen, and connect ideas: part publishing system, part music player, part knowledge map. I designed and built it end to end.
- Motion, not vibration. Its Live2D character moves from a smoothed attack–release envelope and beat phase rather than raw FFT values. The head leads; the body follows 180 ms later, turning audio data into movement with weight.
- Coordinates with meaning. Every post becomes a star whose angle encodes its creation date from the beginning of spring. Adding a new post never moves an old one, so the map can become familiar over time.
- Chinese typography at the edge. Social cards render arbitrary Chinese titles by requesting only the required glyphs for each title—a few kilobytes instead of shipping a complete multi-megabyte CJK font.
- Useful when the network is not. Supabase is the source of truth, while a local cache paints the first screen immediately and preserves the garden when cloud access fails.

On a three-person team, I owned teacher reporting, student profiles, the administration console, and bilingual support. I also handled integration across 13 feature pull requests.
- Built a TypeScript AST check for untranslated interface copy, distinguishing missing translations from Chinese text that legitimately belongs in the source.
- Audited the API after multi-tenancy shipped and found a 374-line unauthenticated route that trusted a
student_idsupplied in the request body; removed the route and its exposed access path. - Turned per-organisation module flags from a passive database column into server-enforced policy across 13 routes.

I write long-form notes in Chinese about algorithms, software architecture, design, and learning—usually by taking an idea apart until I can explain why it works.
