Floor Terminal - Inventory Allocation
Flutter Developer
Case Study Narrative
The business context and technical outcomes of this project.
Warehouse and production teams needed a faster, more reliable way to scan inventory and confirm cut-piece allocations without repeated manual ERP checks or paperwork.
Create a mobile-first tool for operators working on the floor, allowing quick QR scanning and reliable allocation decisions without complex manual entry in busy warehouse conditions.
Developed a Flutter workflow app that scans stock QR codes, fetches product details from an ERP-connected backend, validates allocation quantities, and stores recent inventory and session context locally through Hive for faster, more resilient operational use.
Reduced manual operational friction and improved allocation accuracy by digitizing the warehouse scan-and-confirm workflow while keeping recent stock context available on-device.
Key Engineering Challenges
A detailed breakdown of low-level infrastructure and systems problems successfully solved during implementation.
The Challenge
Problem Statement
Warehouse floor operations were disconnected from the ERP system, making stock lookup and allocation slower and more error-prone. The app needed to support fast scan-driven workflows with clear confirmation and reliable local context for operators.
Research & Decisions
ERP Integration
Connected the mobile workflow to ERP-backed inventory operations using REST requests and session-based authentication with secure token persistence.

Local Caching
Uses Hive to retain recent stock and session context for faster lookups and more resilient on-device workflows in live operational environments.
