I am a software developer living in Sapporo, Hokkaido, Japan. My interests include Wikimedia, machine learning, and all things Python.

Projects

I have been editing Wikipedia since 2010, and I have been a volunteer developer there since 2013. The main projects I have taken are listed below; for a more complete list take a look at my Wikipedia user page.

Sensitive IPs

A framework for flagging IP addresses that belong to politically sensitive organisations. Includes a Lua API for fetching sensitive IP address data, JavaScript code for warning Wikipedia administrators if they are about to block a sensitive IP address, a module for generating summary tables, and libraries to provide easy access to the API from JavaScript.
