I’m setting up a dedicated platform that streamlines end-to-end supply chain operations—everything from order intake to final delivery—so I need a developer who can own the entire build of both the back-end software and its companion mobile app. Core objectives • Design a central dashboard that gives real-time visibility into inventory, purchase orders, and carrier status. • Develop native apps (iOS and Android) for on-floor staff to scan, update, and confirm movements on the go. • Implement role-based access, automated alerts, and API hooks so the system can sync with existing ERPs and carrier systems. Tech preferences I’m flexible on stack, but experience with cloud-first architecture (AWS or GCP), microservices, React/Angular for web, and Flutter/React Native for mobile will help you get up to speed faster. Solid SQL/NoSQL design and REST/GraphQL experience are essential for the integrations piece. What I’ll look for in your bid Show me projects where you’ve already solved similar supply chain challenges or built logistics tools—detail the scale, your specific role, and any performance gains the client enjoyed. Pure feature lists are less useful than concrete results. Deliverables & acceptance 1. Working web dashboard and mobile apps with source code in Git. 2. Deployment scripts and clear environment documentation. 3. A short hand-off session where you walk me through setup, key modules, and how to extend them. Go-live is the milestone; I’ll sign off once I can process a full test order through every leg and generate accurate reports without errors.
