CRM Integration with Pre-Designed HTML/JS Screens
Budget: ₹400 – ₹750 INR
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.
Handover:
Clean, well-commented code
Short technical documentation / README on what was integrated and where.
Tech Stack / Skills Required
Strong experience in PHP (procedural or MVC) and MySQL
Excellent knowledge of JavaScript, jQuery, and AJAX / Fetch for REST APIs
Experience working with HTML5, CSS3, Bootstrap (our UI uses a modern Bootstrap theme)
Good understanding of RESTful APIs (request/response formats, status codes, JSON)
Familiarity with DataTables, Select2, modals, keyboard shortcuts, etc. is a plus
Experience integrating modules into existing CRM / ERP / SaaS applications
Comfortable working with Git and local development environment (XAMPP/Laragon/etc.)
Experience / Profile
Minimum 3–5 years of hands-on experience with PHP + JS.
Have completed similar CRM / ERP module integration projects.
Able to quickly understand existing code and follow our coding style.
[Removed for encouraging offsite communication which is against our Terms and Conditions.]
Can provide code samples or links to previous relevant work.
What We Provide
Access to existing CRM codebase (test environment)
All HTML + JS files for the new screens
API documentation / sample responses
Clear module-wise requirements and expected behaviors
How to Apply
Please share:
Short intro about your experience with PHP + JS + API integration
2–3 similar CRM/ERP or dashboard projects you’ve worked on
Your estimated timeline and hourly / fixed price quote
We’re looking for someone who can start soon and work with us on more modules in future if this project goes well.
