I'm a licensed tourist guide in George Town, Penang, and I build free public transport apps for Malaysia and its neighbours. I run them through TechMavie Digital, my one-person studio. I build with AI-assisted development, and I design, review, host and run everything myself.
Before this I spent seven years as a content writer for brands like Frase, Häfele and Boutir, and I've mapped buses for Moovit as a volunteer since 2019.
Live buses, plus train and ferry departures, across 13 areas of Malaysia, in 13 languages. It runs on data.gov.my open data, and for operators that publish none, like KLIA Ekspres, Penang Ferry, Causeway Link and SRT, I build and maintain the timetables myself. Free on the web; the iPhone app is coming soon.
