About me
Engineer, builder, teacher—and always learning.
I'm Husny Jeffrey, based in Singapore and born in Galle, Sri Lanka. I have spent more than a decade in software quality engineering, and I build products, write practical guides, and mentor people alongside my day job.
My work
At Grab, I ensure the quality of Promos & Rewards features used by millions across Southeast Asia. Lately I've been exploring AI-assisted engineering and shipping my own products, including Nidra, CourtLK, FakePip, Matchly, and Foreman.
