Author & Founder
Seng Chhunsour
Seng Chhunsour is the founder of SlidesClock, a free employee attendance app, and the only developer who has ever worked on it. Every layer of the product, from the phone app employees slide on to the dashboard managers read, is designed and shipped by the same person.
The articles on this site come from that work: how attendance is verified, where time records go wrong, and what small teams actually need before paying for software. They are written from how SlidesClock behaves in practice, not from a brochure.
Building SlidesClock
No agency and no outsourced team. The person who writes these guides also builds:
- iOS & Android apps
- Manager dashboard
- Backend & database
- Attendance & payroll engine
- Infrastructure
- This website
