// about

Hello!

I'm Allan (Seongyeob Im), a software engineer with 20+ years building robust, scalable systems — mostly in Java. I lead engineering at Biddingo, Canada's #1 e-procurement platform, and spend just as much time building my own AI products and tools.

I've shipped software across Canada, the USA, Japan, and Korea — SOA platforms, e-commerce, and mission-critical bidding systems handling millions of transactions. I build with AI agents every day now, but getting the domain model right still does the real thinking.
