Years building web products
Hello, I'm
Daniel Kim
Full-Stack Software Engineer
I design and build reliable web products from interface to infrastructure — combining thoughtful user experiences with scalable application architecture.
01
Profile
Engineering with the whole product in mind.
I’m a full-stack software engineer based in Auckland, working across product development, frontend engineering, backend systems and cloud deployment.
I enjoy turning complex requirements into clear, maintainable software — whether that means designing a data model, building an intuitive interface, integrating APIs or improving the reliability of a production application.
My approach combines technical problem-solving with product thinking. I care about how software is structured, but equally about whether it is understandable, useful and dependable for the people using it.
