AI Vision Scanner / OCR
Mobile document scanner and optical character recognition utility app.
The Problem
Manual document transcription and receipt scanning are prone to input mistakes and data security concerns when sending private records to cloud APIs. This utility provides professionals with an on-device camera scanner that instantly isolates documents, runs local optical character recognition, and exports clean formatted text without cloud dependency.
What I Built
Delivered end-to-end in milestone phases, with a verified working build at each stage and full source code handover.
Key Technical Decisions
On-Device Machine Learning: Utilized local on-device ML Kit vision models for zero-latency scanning without sending private documents over external servers.
Reactive Camera Bridging: Implemented high-performance Flutter camera stream listeners for real-time bounding box rendering.
Results & Client Impact
Engineered an offline-first mobile utility achieving sub-second text recognition from receipts, invoices, and business contracts.
Application Gallery
Verified production screens from the Barrera's Remodeling Inc Flutter application.
