Project Name: Custom Contractor Management System (Replace Tradify)
Project Type: Full custom web + mobile application
Overview: We are building a full contractor management system to manage engineers, subcontractors, jobs, timesheets, invoicing, GPS tracking, and reporting. The system must be scalable (currently 9 engineers, future 500+), secure, GDPR-compliant, and integrate with Sage first and Xero later.
We need a freelancer (or small team) to develop both backend + frontend, mobile apps, and database according to detailed specifications.
