01 · PROJECT CONTEXT

The product challenge

Check-in combines identity/document capture and guest-provided information, so the app needs a clear sequence and dependable API submission.

MY CONTRIBUTION

Flutter implementation for scan/capture flows, check-in steps, API integration and local storage.

02 · IMPLEMENTATION

Implementation & engineering decisions

01Built QR scanning and document/MRZ scanning steps.
02Integrated guest photo capture and digital signatures.
03Connected the check-in sequence to APIs.
04Used local storage to support the app workflow.

ENGINEERING NOTES

Where the implementation needed care

Architecture

Flutter client coordinates scanning, camera/signature capture and API submission as a guided check-in workflow.

Key challenge

Make a multi-step identity and check-in process understandable on a mobile device.

Delivered
