Engineering principles
Standards that guide our technical decisions.
Maintainability
Clean module boundaries and explicit code structure ensure systems remain understandable and adaptable over years of use.
Data modeling
Database schemas directly reflect real-world business documents: stock receipts, sales, settlements, and returns.
Operability
Audit logs, permission controls, and clear error diagnostics are built into the core architecture from day one.
Incremental delivery
Systems evolve through small, verified releases that protect active business operations from disruption.
Cross-platform status
Current and planned runtime targets.
Web Browser Environment
Next.js / React / TypeScript
Primary browser workspace for management, analytics, inventory, and POS operations.
Desktop Workstation App
Tauri / Vite
Native desktop builds for Windows, macOS, and Linux retail and warehouse stations.
