// about

Hello!

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

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