Ruiyang — Engineer + Product Owner

I build small, sharp software products and ship them under my own name. Twelve years across automotive, finance, web3, AI and gaming. CFA · ASA · M.S. Computer Science (UT Austin) · B.Eng. EEE (NTU).

Currently shipping two products:

Memdora — turns anything you read into flashcards, then resurfaces them with FSRS-6 spaced repetition so it sticks.
Brier — a flight simulator for trading judgment; commit to a historical setup blind and get scored on calibration, discipline and expectancy.
