• Adaptation to pollution restrictions (ZFE).
• Reporting of breaks, stops and travel times.

Traceability and inventory

• Inventory management and item detection via UHF, HF, NFC, 2D and QR code.
• Compatibility with Chainway and Zebra industrial PDAs.
• Proof of visit: photo capture and QR code assignment.
• Real-time synchronization with the back office.

Refactoring and performance

• Progressive migration from Java to Kotlin with MVVM architecture.
• Fixed all identified memory leaks.
• Optimized loading and startup times.
• Audited usage limits on industrial PDAs.

• International rollout: Brazil, Canada, Poland.
• Adaptation to local customs and regulatory constraints.
• Smooth and reliable app used daily by hundreds of field agents.
