This project model was an online school, which its main objective was to replace the Bookly form functionality for booking events and checking the availability of service providers ( staff members ), so I worked on a custom empty plugin blueprint on these features:

•  Integration between different Bookly components ( events calendar, checking availability for service providers including ( schedules, breaks, days off, holidays, and appointments ).
• Conversion between different timezones regarding DST for both customers and service providers.
• Shortcode attendance table for school appointments with total hours and late mins calculations.
• Setting cron jobs to update the custom table with data from Keap and Zoho API.
• Post and get data to Gravity forms using rest API, and native functions.
• Extending Bookly calendar template and classes for customization.
• Making custom table for billing status using CRM data to automate actions (activate, suspend, and cancellation) of programs based on collected data.
