What it does

Who it serves
Employees, managers, HR teams and administrators.
Product purpose
Hybrid web and local-first desktop HR operations.
  • Employee records, tenant scope and role-aware self-service.
  • Policy-backed leave and schedule-aware attendance.
  • Audit history and durable offline desktop synchronization.

How it works

  1. Employees and managers use the Next.js portal for self-service.
  2. HR/admin users can work through the Wails desktop console and local SQLite storage.
  3. The durable sync queue sends authorized operations to the Go API.
  4. PostgreSQL remains the authoritative system of record; synchronization handles conflicts explicitly.

Current scope

Local-first refers to the desktop console. The cloud database remains authoritative. Payroll-ready attendance boundaries do not mean a complete payroll-processing product is included.

Contributor notes

Run locally

Configure .env from example; docker compose up --build (demo setup)

Design decision

Cloud HR data is authoritative; the desktop uses a local store and sync queue.

Trade-off

Offline operation adds synchronization, conflict resolution and local-data protection concerns.

Unfinished

Default Compose is demo-only; full payroll and production layers remain unfinished.
