CRM Database Sync API e.g.- apidog

I'm looking for a precise solution to unify the databases of my two Live Laravel-based CRMs. Here's what I need:

- Develop an API to connect and synchronize databases of both CRMs in real time.
- Ensure the following data types sync thoroughly:
- Contact details
- Sales transactions
- Calendar events
- HRM Details of employees
- Bidirectional synchronization: changes in one CRM should mirror in the other.

IDEAL FREELANCER PROFILE:
- Proficient in Laravel and API development
- Experience with CRM platforms
- Strong database management skills
- Reliable, with a track record of successful integrations

PROJECT GOALS:
- Seamless data integration
- Robust, error-free synchronization
- Transparent and secure data handling

Please, only apply if you have a strong background in all the requirements mentioned. Looking forward to your bid!
