• Implement final business onboarding/configuration steps
• Prepare and submit the app to App Store and Google Play, addressing any review feedback

• Strong API integration skills (payments, accounting, messaging)
• Experience with OAuth2, token refresh, and webhook handling

We Provide
• Full access to the existing app codebase (GitHub)
• API keys & sandbox accounts
• Test data and workflow documentation
• Detailed list of remaining tasks & priorities

Engagement Details
