GATT System
Travel-agency ERP / CRM — the centerpiece
- A full travel-agency operating system: sales, finance, HR/payroll, courier logistics, marketing and document workflows in one multi-tenant platform.
- Sales pipeline with accountant review, record-locking, debounced inline editing and observer-driven cache versioning.
- Finance: Paymob dual-branch gateway, HMAC webhooks, hourly reconciliation, receipts and credit vouchers.
- 4,000+ line HR/attendance/payroll engine — biometric multi-DB reconciliation, leave accrual, late-penalty deductions and doc-expiry compliance.
- Vision PDF pipeline: Claude vision → coordinate-based, form-agnostic autofill for visa and travel forms.
- OAuth2-secured MCP server + AI Skills API with 4-provider LLM routing; in-CRM mailbox with a hand-written ManageSieve compiler.
- Native Android WebView app (reproducible Docker build) and a self-hosted Chrome extension with CRX3 signing + Omaha updates.
