Wayturn · Backend Engineer · Taiwan
I’m Wayturn Hung （洪偉騰）, a backend engineer in Taiwan. I work on enterprise system modernization and build AI developer tools. This is where I document the work, the decisions, and the questions that follow.
I plan technical discovery and a representative POC for a legacy enterprise system moving toward .NET 10 and ASP.NET Core, with existing business behavior as the starting point.

03An open question
How do AI search systems discover a person and make sense of their work? This site is my ongoing experiment. I document the changes, the test conditions, and what I can actually observe.
