Peanut Supply Chain Tracking App

I'm looking to develop an app that connects peanut farmers with processing factories. The primary function of this app is to facilitate contract documentation, identify fields used to plant, chemical spaying, water application (rain or irrigation) and to track peanut delivery, quality, and payment.

Key functionalities should include:
- Admin tab to track contracts, MRLI status, etc
- Financial tab - show seed advances, harvest bag orders etc
- Fields tab- geotag each field, size, cultivar , drill density, drill date, chemical application, water application (and end of season cost benefit analysis
- Request transport - app to request transport and track transport
- Recording quality and payment details per load, allow the load to be linked to a field or fields to allow for post season anlysis. App must be able to take an end of day feed from SAP backend
- Integrating data for farmers, factory staff, and transport drivers

Ideal skills and experience:
- Mobile app development
- Experience with supply chain management systems
- Familiarity with agricultural industry apps
- Strong UI/UX design skills for user-friendly interface

Please provide a portfolio showcasing relevant projects.
