I run a small taxi operation and quickly realized that managing it with spreadsheets and memory was unsustainable. Service dates get missed, drivers report inconsistent numbers, and there's no way to know if a vehicle is actually profitable until it's too late. Trogern was born from the need to bring software-grade visibility into a business that traditionally runs on paper and trust. The goal is simple — know exactly what's happening across the fleet, make better decisions, and eventually scale the tooling to other operators facing the same problems.

The system is built on a multi-tenant Firestore data model with strict domain separation — companies, drivers, vehicles, services, income logs, and expense logs each live in their own collections with relational references. The admin dashboard is a React SPA (Vite + TypeScript) using Redux Toolkit Query for server-state management and Shadcn UI for the component layer. The backend runs on Express with the Firebase Admin SDK, deployed as a containerized service on Google Cloud Run. Authentication flows through Firebase Auth with custom claims for role-based access. A Flutter mobile client is in development for drivers and field operators, sharing the same backend API. CI/CD is handled through Cloud Build with automatic deployments to Firebase Hosting.
