My current site needs a complete refresh on both the client and server sides, and I want it built with solid PHP and Java foundations. Frontend scope • Implement a secure user login and registration flow that ties neatly into the backend session logic. • Build interactive forms that validate in real time and feel snappy on desktop, tablet, and mobile. • Ensure every page remains fully responsive so the layout adapts smoothly to any screen size. Backend scope • Design and manage the database structure, keeping it lean yet flexible for future features. • Integrate external APIs where required so data can move in and out of the platform seamlessly. • Handle user authentication with best-practice hashing, session handling, and role management. Acceptance criteria • All frontend features render correctly in the latest Chrome, Firefox, and Safari browsers. • API endpoints return the expected JSON responses with proper error handling. • No security warnings from standard scanners (SQL injection, XSS, CSRF). • The finished code is cleanly commented and delivered through a Git repository. If you are equally comfortable writing performance-minded PHP and Java code, this project is ready for you to dive in.
