FIG. 1Visits are GPS-stamped on the device; the API serves LOGO account statements and queues push notifications.

01Problem

Field sales reps noted visits on paper and called the office to learn customer balances. Managers had no visibility into who was where in the field.

02Solution

I built a mobile app with React Native 0.81 + Expo 54 (TypeScript) and a JWT-protected Web API on ASP.NET Core 8. Visits are GPS-stamped, manager assignments are delivered via server-side Expo Push, and the customer's LOGO account statement can be viewed in the field.
