I am looking for an experienced WordPress Plugin Developer (PHP + JS) to audit, fix, and complete a custom-built booking and billing platform. The system is for shared rooms that allows users to book rooms by the hour. They are charged monthly. The pricing system is dynamic and is based upon the number of hours booked within each calendar month. The system is already functional in parts, but several core components—especially dynamic pricing and cancellation logic—require expert debugging, refactoring, and stabilisation. You will work on an existing codebase (custom plugin + custom API + JS calendar interface) and ensure accurate pricing, clean data handling, smooth booking flows, reliable cancellation logic, and polished UI/UX across user and admin dashboards. This is not a simple theme task — I need someone comfortable with complex business rules, algorithmic billing logic, database consistency, and custom WordPress development. I won’t respond to automatically generated responses that are clearly written by ai.
