oimrqs ops public proof-of-process / synthetic marketplace MVP / no app-store claim

React Native / Expo MVP concept proof

A mobile MVP architecture a technical buyer can inspect before handing over the product brief.

This proof shows how I would structure a three-role marketplace/service app in React Native and Expo: consumer flow, provider work queue, support/admin visibility, API integration, cache/persistence, acceptance criteria and iOS/Android validation.

Honesty label: concept/proof-of-process. This is not a shipped production app, client case, App Store listing or fake portfolio claim.
Buyer risk

Technical buyers need to see app structure, not a generic mobile mockup.

A React Native MVP pitch is stronger when it shows role flows, navigation, API state, offline tolerance, error handling and validation boundaries before the buyer shares credentials or commits to a build.

Target stack

Expo Router, TypeScript, Tamagui, TanStack Query, Zustand and MMKV.

The proof assumes React Native 0.78+ or equivalent current project baseline, Expo Router for file-based navigation, Tamagui/design tokens for UI consistency, TanStack Query for server state, Zustand for app state and MMKV for local persistence.

Proof left

The useful output is a reviewable first sprint, not a vague promise of an app.

A bounded pass should leave architecture notes, feature folders, API contracts, fixtures, state decisions, iOS/Android smoke checks, known risks and a next-sprint backlog the buyer can inspect.

Buyer-readable architecture

Three roles, one shared data contract, clear failure states.

01

Consumer app

Search, request details, quote review, booking, status timeline, messages/notes and safe receipt view.

02

Provider app

Job queue, quote draft, schedule confirmation, offline notes, photo attachments and status transitions.

03

Support/admin view

Exception queue, manual review flags, stale requests, dispute notes and operational visibility without account bypass.

04

API boundary

Typed fetch client, auth headers, zod-style response checks, normalized errors, retry policy and optimistic updates only where safe.

05

State and persistence

TanStack Query owns server cache, Zustand owns app/session UI state, MMKV stores safe drafts/preferences and mutations queue deliberately.

06

QA gate

Device smoke checks, loading/empty/error states, deep links, offline/retry behavior, form validation and release-readiness notes.

File-tree proof

A feature-folder structure keeps the MVP inspectable as roles grow.

API and state pattern

The first pass proves loading, empty, error, retry and offline-safe behavior.

Server state

TanStack Query keys are role-aware: `['requests', role, filters]`, `['request', id]`, `['provider-jobs', status]`.

Mutations

Quote submit, booking confirm and status changes use explicit success/error states and conservative optimistic UI.

Persistence

MMKV stores safe local drafts, preferences and a small retry queue; no tokens, secrets or payment data are exposed in this proof.

UI states

Every screen gets loading skeleton, empty copy, validation message, API error banner and retry affordance before polish.

iOS / Android validation

Acceptance checks a technical buyer can ask for after the first sprint.

Check Evidence Done when
Navigation Expo Router role groups, deep-link smoke pass consumer/provider/support flows open expected screens
API states loading, empty, error and retry screenshots buyer can review failure behavior without code spelunking
Offline draft MMKV draft persistence note and replay boundary safe draft survives app reload; sensitive data is excluded
Device pass iOS simulator and Android emulator notes primary flows avoid layout clipping and blocked inputs
Handoff architecture note, env list, known risks, next sprint buyer has a clear continue/stop decision

Use when

This proof fits a buyer evaluating React Native / Expo MVP capability.

  • Three-role service marketplace, booking, field-service, job queue, support queue or internal mobile MVP.
  • Buyer asks for GitHub/portfolio proof and wants to see architecture, state/data decisions and validation discipline.
  • The first paid slice is a prototype, scaffold, architecture pass, feature first sprint or rescue of an existing Expo app.

Do not use when

This proof is not a production app claim.

  • Buyer requires a real app-store published React Native case, store analytics, production users, reviews or client references.
  • The job needs KYC, app-store account ownership, paid Apple/Google billing, payout, sensitive credentials or security/account changes.
  • The scope is native Swift/Kotlin-only, game engine work, full backend ownership or guaranteed launch approval.
