Our client in Japan, specializing in geotechnical surveys and engineering, conducts detailed site investigations for infrastructure projects, emphasizing accuracy, efficiency, and safety. Traditional surveys used paper notes and manual reporting, causing delays and inconsistencies. The project aimed to digitalize workflows, allowing field operators to collect data on-site and providing administrators with a platform for data management and reporting. We built native iOS and Android apps, expanding our skills. Recently, we focus on cross-platform and hybrid apps, creating user-friendly interfaces with consistent functionality and responsiveness across both platforms devices.
