One domain, four apps
Customer, vendor, rider and admin share a DDD + MVVM layering (framework → repository → controller → UI), so a feature lands in the same shape everywhere.
Parcel walaa.
A hyperlocal food and parcel delivery platform: four Flutter apps for customers, restaurants, riders and ops, all on one Express + Supabase API.
P1 — Approach(How it's built)
Mock-first development
A Dio interceptor swaps the network for a seeded mock API with a single flag (MOCK_API). Every screen below was captured that way: real build, no production data.
Brand as a system
A written brand guideline covers tokens, elevation, motion and iconography. Yellow #FFCA26 against a near-black, Neue Haas Grotesk, and 1.8px rounded strokes.
