Mobile Developer Needed for MVP with API and Email Parsing at Upwork (Expired)

I’m looking for an experienced mobile app developer to build an MVP for a consumer-facing application. The app will involve:

Handling OAuth logins (e.g., Google, Microsoft)

Parsing inbound emails or forwarded emails to extract structured data (QR codes, PDFs, metadata)

Securely displaying and transmitting QR codes/images to other users inside the app

Scheduling and tracking tasks (user → driver handoff style workflows)

Strong emphasis on encryption, security, and clean UX

Proven experience shipping iOS/Android apps (React Native, Flutter, or native Swift/Kotlin — open to discussion)

API integration experience (OAuth 2.0, REST/GraphQL, third-party SDKs)

Experience with Gmail/Outlook API integrations or email parsing pipelines

Ability to design and implement task flows: user requests → task creation → driver view → status updates

Familiarity with secure file handling (QR codes, PDFs, images)

Bonus: experience with geo-location APIs, push notifications, or marketplace-style apps

Someone who can move quickly on an MVP, but with production-ready code quality

Ability to advise on architecture choices (stack, backend, hosting, auth)

Strong communicator — I’d like to collaborate closely and iterate fast
