Came to Cambodia about 4 years ago and realised it lacks a lot of educated engineers, technicians and specialists in almost every sector of commerce.
Started as a small time repair shop for all Android, Windows, Mac & Linux devices. Soon enough found that all the POS systems are either very outdated or business are still writing everything down on paper receipts.
Looked for an open source POS, eventually started working with SambaPOS and now I have about 30 clients across Cambodia. Looking forward to expanding that pool.
