Reports React is my preferred stack because I want something that runs smoothly on desktop, tablet, or phone without separate apps. If you feel another framework is genuinely better, outline your reasons and how you will still deliver the same snappy, mobile-friendly experience. Deliverables • Full React source code with clear component structure • Responsive UI tested on standard mobile and tablet viewports • API documentation for future integrations • Database schema and migration scripts • Deployment guide (Docker or similar) Acceptance criteria • Creating or updating a purchase order adjusts stock on delivery confirmation without manual input • Role-based permissions prevent unauthorised access to admin screens • Reports generate accurate figures that reconcile with sample data sets I provide • Interface loads in under two seconds on a mid-range mobile device over 4G That’s the complete picture; I’m ready to move as soon as I know your approach and timeline.
