Check24-Hostaway API Sync -- 2

I need a developer who can create a reliable bridge between the Check24 platform and Hostaway. The sole focus is data synchronization—no payment processing or additional booking management logic for now.

Scope
• Pull new and updated booking data plus related customer records from Check24 and push them to Hostaway, and vice-versa where applicable.
• Run the sync every minute with solid queue or webhook logic so neither side is overloaded.
• Map all relevant fields (guest details, reservation status, dates, channel references, etc.) and handle edge cases such as cancellations or modified stays.
• Build clear error handling, retry logic, and concise logging so I can audit what was sent and when.
• Deliver concise setup instructions along with commented source code (preferably Python or Node.js, but I’m open to other robust solutions).
• Provide a brief test suite or Postman collection so I can replicate the calls and confirm everything works before we go live.

Access to both APIs and basic credentials will be supplied once we start. If you’ve previously integrated travel or property-management APIs, please highlight that experience.
