Budget: $15 – $25 AUD
We are seeking an experienced Full-Stack Developer (or small team) to design and build a new in-house commodity trading and logistics platform, replacing our 30-year-old legacy system currently used for day-to-day operations.
This platform will manage all aspects of our business, including contacts, contracts, logistics dockets (LDD / LRR), products, and financial transactions, with full reporting and integration into existing systems such as MYOB.
Key Project Scope
Objective:
To modernize and streamline internal business systems by replacing our aging, Clarion-based software with a scalable, web-based solution.
Core Modules:
Contacts — Segmented by type (Broker, Customer, Supplier, Freight, Grower), with credit limits and roles.
Products — Seed, oil, meal, and by-products, with specification data and quality metrics.
Contracts — Sales and purchase contracts with full status workflows, pricing models (fixed, basis, market index), and document generation.
Logistics — Load Despatch Dockets (LDD) for sales and Load Receival Dockets (LRR) for purchases, including weighbridge integration.
Finance — Invoice, payments, and credit management, integrated with MYOB.
Reports & Dashboards — Real-time visibility on position, exposure, and margin data.
User Roles & Permissions — Trader, Admin, Logistics, Finance.
Integration Requirements:
MYOB for financial data sync.
Weighbridge ticketing system.
PDF contract/invoice generation.
Technical Preferences
Frontend: React.js (Tailwind or similar)
Backend: Node.js (Express) or Python (FastAPI/Django)
Database: MySQL or SQL Server
Hosting: On-premises Windows or Linux server
Project Phases
Phase 1 (MVP) — Contacts, Products, Contracts, and Logistics modules (6–8 weeks)
Phase 2 — Finance integration, reporting, dashboards, and extended automation
What We Expect
Clean, modular, well-documented code
Unit and integration testing
Deployment and configuration documentation
Experience in legacy system modernization or data migration highly valued
Ongoing maintenance and support post-launch
To Apply
Please include:
Examples of similar systems you’ve developed (preferably in trading, logistics, or ERP).
Suggested architecture / tech stack outline.
Proposed timeline and cost estimate.
Overview of relevant experience (especially with system migrations).
