Projects

01 Structured debate platform

Respond

A one-on-one debate platform built to make disagreement slower, fairer, and focused on reasoning instead of crowd dynamics.

  • Keeps both sides anonymous during debates so arguments are judged on merit, not identity.
  • Uses turn-based structure, time boundaries, and explicit endings to prevent endless, low-quality arguments.

02 Vietnamese exam practice

Ngàn Lá

An all-in-one Vietnamese high school exam platform that combines discovery, practice, review analytics, and AI help.

  • Lets students browse by subject, curriculum, textbook, or topic and start practicing directly on the web.
  • Goes deep on review with timeline insights, session replay, and progress tracking after every exam.

03 AI vocabulary learning

Vocaxis

A vocabulary learning app designed around the real bottleneck in spaced repetition: creating good cards quickly.

  • Uses an AI-generated learner-friendly dictionary so users can search a word and add it to a deck in seconds.
  • Pairs FSRS scheduling with saved collections and contextual AI help inside the review flow.
