Overview
- A tax-revenue collection system for the Khyber Pakhtunkhwa (KPK) government, digitizing collection workflows that previously depended on paper and on a stable internet connection. Alongside the web platform, it includes a desktop application that keeps working offline.
The problem
- Revenue collection happens in offices and in the field, where connectivity is unreliable. An online-only system would stop work whenever the connection dropped, while paper records left gaps in accountability. The system needed to keep collecting reliably and securely either way.
My role
- As a full-stack developer (Angular + Node.js), I built collection features, role-based access control, and Firebase integrations, and developed the offline-capable desktop application.
Approach & architecture
- Built an offline-capable desktop app with ElectronJS + SQLite3 that stores work locally and syncs when connectivity returns.
- Implemented role-based access control (RBAC) so each user sees and acts on only what their role allows.
- Integrated Firebase Storage for documents and Firebase Cloud Messaging for real-time notifications.
- Built collection-workflow features in the Angular web platform backed by Node.js APIs.
What I learned
- Designing for offline-first from day one is far easier than retrofitting it — local storage and sync shape the data model, not just the UI. In GovTech, predictable, traceable workflows build the trust that makes adoption possible.
