His Taiwan Cinema profile mentions he did continuity for the movie 我在死牢的日子. The name in the credits is actually 薛道聲 (in our DB but with the wrong family name: 薜道聲)
Just as some additional proof, this court decision: https://www.tipo.gov.tw/tw/dl-19610-933 ... 16ffb.html
confirms they are the same person:

原告 薛少軒
[...]
薛道聲（原告之舊名）

If nobody objects I will merge them soon and also change the primary name to Brian Shiue.
