F&B Digital Transformation & AI Engineering

Centralized Digital Recipe & Kitchen Standard System

An enterprise-grade Progressive Web App (PWA) transforming printed kitchen wall SOPs into a unified, cloud-synced digital operations platform across multi-brand and multi-branch restaurant networks. Engineered with human-led database schemas and API specifications, and fully coded by Claude AI — proving how non-technical PM leadership can rapidly build enterprise software without massive dev teams.

⚙️ Admin Central CMS

3-step creation wizard (Ingredients → Cooking Steps → Quality Check) with batch Excel/CSV import/export, role-based access control, and master recipe synchronization.

📱 Front-Store Kitchen PWA

Cross-device station display with step-by-step cooking timers, Gold Standard reference photos, and pre-serve quality checklists for kitchen staff.
