This project is an internal web application that will sit behind our firewall and serve several business units at once. I need a seasoned developer who can take it from database schema through deployment and hand-over documentation. Core functionality • Role-based access: at minimum Admin and Operator, with the ability to add more roles later • Multi-company tenancy so records stay completely isolated by company • Clean form screens that feed a well-structured relational database • One-click PDF and XML output from any stored record • Real-time dashboards for key KPIs and ad-hoc reports • Solid API layer that connects to payment gateways, CRM systems and our Facturación (electronic invoicing) provider Deliverables 1. Source code in a Git repo with clear commit history 2. Normalised database design and migration scripts 3. Fully functional API integrations, tested with sandbox and live credentials 4. Responsive dashboard UI with charts/tables driven by the stored data 5. Basic user manual and setup guide Acceptance criteria • All core features accessible only after login and correctly restricted by role • Data entered for one company is never visible to another • Successful creation of PDF/XML documents that match the sample templates I will provide • External calls to the three target services return expected responses and are logged for audit • Page-level load times under two seconds on a modest VPS I value clear communication, regular progress demos, and clean, well-commented code. Please share links or screenshots of similar dashboards or API-heavy systems you have built, along with your preferred tech stack and estimated timeline.
