I'm Rayson. I design and build software, and I've been at it since 2002.

Now

I’m building MoneyMama, an AI money assistant for Malaysians, at FinLit Media. I work across its app, backend and internal tools with AI coding agents. Lately I’ve been writing about making Mama faster, improving her knowledge base and the bugs we’ve found along the way.
