A field-service operator needed a platform to manage drivers, rides, contracts and document generation across teams and locations. We delivered a NestJS API with TypeORM and MySQL, a dedicated mailer service with Handlebars templates, an Angular 11 operations portal with maps and exports, and a React Native field app with background geolocation, camera, signature capture and Firebase services.

Field-service operations live or die on the quality of the mobile workflow and the reliability of generated documents downstream.
Drivers and field teams need a mobile app that handles maps, signatures, photos and connectivity gaps.
Contracts and reports must be generated, converted and stored without manual steps.
Operations leaders need a portal with the same data the field sees, in real time.
We split the platform into focused services and wired them into a coherent integration layer.
