Profile

I'm an engineer and former researcher in human languages, machine learning and web systems. I love making and discovering; sometimes I even write about it.

I tried to model what language learners know to better help them learn, and turned these models into tools for studying Japanese and Chinese. Following text mining interests to NICTA, I began analysing medical text corpora. This sparked my interest in machine reading and big data. I joined 99designs to learn how to serve larger audiences, and stayed to delve into the rich data that comes with customer interaction.

Large datasets help to unveil the mathematical beauty underpinning the world. I like to discover and share this beauty, and impact peoples lives.

Projects

  • The Great Language Game: learn to distinguish between spoken languages
  • marelle: test-driven sysadmin through logic programming
  • doko: a command-line tool for determining your current location
  • colorific: library for detecting significant color in designs
  • anytop: an ncurses frequency visualisation from streaming input.
  • simsearch: an open source visual similarity search for Japanese kanji.
  • foks: an intelligent dictionary for learners of Japanese.
  • kanji tester: a study tool for JLPT levels 3 and 4 centred around adaptive testing.
  • cjktools: a Python library for working with Japanese and Chinese dictionaries.

Some of my work is open-sourced, and is available on Github or Bitbucket.
