Developer site

Practical tools by Evan Wong.

I build lightweight apps and web tools for focused everyday workflows. My current products include MJ Actuary, a Mahjong scorekeeping companion, and ClearCanvas, a web tool for removing image backgrounds.

MJ Actuary is a scorekeeping utility only. It does not provide gambling, betting, casino games, real-money gameplay, payment processing, prize redemption, online play, or matchmaking.

MJ Actuary

A mobile Mahjong scorekeeping companion for live table games, with support for dealer streaks, draw rounds, bonus pool, history, statistics, and HK-style Taiwan Pull/Kick settlement.

ClearCanvas

A browser-based image tool for removing photo backgrounds. It is a separate web product from MJ Actuary and is available at clearcanvas.app.
