TargetDesk.

I built TargetDesk as a Laravel API and an Angular frontend designed together as one system, sharing the same permission model on both ends. Every authenticated request runs through company-scoping middleware that resolves the current tenant and applies it globally, so isolation is guaranteed at the framework level rather than relied upon per-query — with a clean bypass path for platform-level super-admin access. On top of that, I implemented a full accounting engine modeled on the French Plan Comptable Général: journal entries, general ledger, trial balance, and bank-transaction reconciliation, alongside supplier invoicing and a rule-based commission engine that calculates, splits, and audits commissions automatically. Access control runs on a permission system with dozens of module-level actions, each independently scopable to System, Team, or Personal — enforced identically by the API and by the Angular client, down to matching permission-string formats. The call-center module integrates with Ringover for live call and SMS history, feeding directly into complaint tracking and supervisor/manager reporting.
