Work
Tools I built because I wanted them to exist, and still use. The bigger ones have a full write-up. The small ones just do their job.
They sit on top of ten years of enterprise product work: a global Linux estate, an intrusion detection product, and government cloud carrying a million API requests a minute. The tools here are the same work at a smaller scale, with the edges tested. There's more on the About page.
Parsnips
Every sitting of Singapore Parliament, published with the summarised passages highlighted inside the full transcript. Every summary sentence points back at the turn it came from, and a pipeline picks up new sittings on its own.
SG Family Life
Singapore family money, worked out with real numbers: benefits year by year from birth to 17, the housing grants stacked on one purchase, CPF projected to 55, and the reliefs that are claimed rather than given.
SteadyCert
800+ pages of CISA review manual, turned into 372 illustrated sections with 372 practice questions. Each concept is attached to something you can picture, instead of being one more wall of text.
