3. About the Author
KZ (Licensed Architect / Developer of FAMI-KAN)
A licensed architect by profession and a parent of two. Having served as the organizer for countless trips and events since student days, KZ spent nearly two decades wrestling with the hassle of splitting bills — and eventually built the bill-splitting app FAMI-KAN single-handedly, despite having no prior programming experience. The articles on this site are written and supervised based on this first-hand experience and the insights gained through developing the app.

Our articles are written based on the real experience and expertise of KZ, our developer and author, with fact-checking. Descriptions of app features are verified to match the actual specifications. While we monetize through advertising, ads never influence our editorial content.
