Technical Quality Control Advisor – React Native

We are seeking an experienced Technical Quality Control Advisor to review and validate the work of our development team on a React Native marketplace application.

This role is NOT for development work. It is strictly for oversight, review, verification, and technical confirmation that implementation is correct, secure, scalable, and production-ready.

We are currently investing into active development and need an independent expert to ensure all work delivered meets professional standards.

Project Overview

Platform:

Local services marketplace

Mobile App:

React Native / Expo

Backend:

Supabase

Payments:

Stripe

Hosting:

VPS (Ubuntu / Hestia)

Features include:

Job posting & applications

Business Pro accounts

Service listings (Business only)

Stripe payment integration

Role-based permissions

Admin controls

Security enforcement

Responsibilities

• Review feature implementations for correctness
• Confirm backend logic aligns with requirements
• Validate role-based access control
• Review Stripe integration & payment flow
• Confirm Business Pro restrictions are properly enforced server-side
• Check database structure & relationships
• Identify security vulnerabilities or architectural risks
• Confirm mobile UI is correctly connected to backend
• Review code quality & scalability
• Provide written QA reports with clear findings

You will NOT be writing core features — you will be auditing them.

Ideal Candidate

• 5+ years React Native experience
• Strong Supabase / Postgres knowledge
• Stripe integration experience
• Experience auditing freelance dev work
• Strong backend architecture understanding
• Familiar with VPS deployments
• Clear communicator
• Able to detect shortcuts, technical debt, or poor implementation

Deliverables

• Written technical review of each completed milestone
• Clear list of issues (if any)
• Confirmation when work is properly implemented
• Recommendations for improvements if needed

We expect:

• Weekly milestone reviews
• Occasional live code walkthrough calls
