      Mobile App Development Review from Vasko Markovski

      Our company hired them to create an app designed to help expatriates find housing. A project manager and two developers from Saigon Technology worked closely with our team for the app's development. At the start, their team and ours gathered the information needed for the project and planned out how to build the product. They then designed the app's interface and added features. In the end, we launched the app successfully, and our client was satisfied with it.
