Title: Integrate Pre-Designed HTML + JS Screens into Existing CRM (API Integration) Description: We already have a set of pre-designed HTML + JavaScript pages (Bootstrap + JS) for our CRM module. We are looking for an experienced PHP + JS developer to wire these screens with our real APIs and integrate them cleanly into our existing CRM project. This is not a design job – the UI is ready. Your main work is backend integration, JS logic, and data flow. Scope of Work Review our existing CRM codebase (PHP/MySQL) and understand current structure (login, auth, routing, etc.). Integrate our pre-built HTML/JS pages into the CRM: Replace dummy/static data with live API calls (AJAX / Fetch). Connect forms, filters, search, pagination, and modals to real endpoints. Implement create / edit / delete / list operations using our API structure. Handle: Form validation (front-end + basic backend checks) Proper error handling and user-friendly messages Session / authentication checks for secure access Optimize JS code where needed (modular functions, reusable components). Ensure responsive behavior and cross-browser compatibility. Final testing with sample data and small fixes based on feedback.
