AI sales agent on Messenger An Arabic-speaking conversational agent that handles the full sales funnel for an abaya brand — from product discovery to captured order.

Principles I actually enforce in code review — not poster material.
- Backend services own all business logic. Agent tools are thin adapters, nothing more.
- The database is the contract. If the schema doesn't express it, the invariant doesn't exist.
- Money is an integer. Fils, not floats. Commissions in basis points.
- State is derived, events are appended. Order status is computed, never mutated in place.
- Arabic-first, not Arabic-translated. RTL, dialect, and local commerce norms are design inputs — not a post-launch patch.
