Apps

KRAIL

Sydney public transport shouldn't be stressful. KRAIL covers trains, buses, ferries, metro and light rail: real-time, accessible and open source. It is written in Kotlin Multiplatform with a Ktor backend.

I presented how it is built at Google I/O Extended Brisbane 2025.

Sumi

A daily Sudoku that respects your attention. Ink on paper, five difficulty levels and streak tracking. No noise, no ads, no dark patterns. Just the puzzle.

Huezoo

A colour perception game built around Delta-E science. Find the outlier among near-identical hues. It starts forgiving and gets quietly brutal, and it ranks you by accuracy, not just speed.

AI tooling

ASTRAMAN

A small team of AI agents that builds apps the way I would. Every app starts from the same tested base, so they only write what is new.

How a build runs

  1. Plan. Read the designs and plan the work.
  2. Build. Write the code, one step at a time.
  3. Check. Review each step before the next.
  4. Learn. Note what went wrong for next time.
