About the project with FieldOne Systems
IT Craft partnered with FieldOne Systems to redesign their legacy desktop software into a modern, cloud-native solution. We provided full-cycle cross-platform app development, including both Android and web components.
The solution enables field technicians to access job schedules, receive optimized routes, update tasks on the go, and securely sync data with the back office — all through a dedicated Android app and connected web platform.
FieldOne aimed to move away from their outdated infrastructure and adopt a scalable platform that supports real-time coordination between field teams and dispatchers. Cross-device accessibility and Microsoft integration were key.
The main objective was to streamline field service operations, boost productivity, and modernize the user experience. This transition laid the foundation for future growth and contributed to FieldOne’s acquisition by Microsoft.
