A BIT OF CONTEXT / 05

Engineering shaped by curiosity.

I’m from Miri, Sarawak, and studied Software Engineering at Universiti Putra Malaysia. I enjoy the moment a promising idea becomes a system: a model connected to its data, an API backed by sound decisions, and a product that makes the result understandable.
