I'm in need of an experienced node.js developer who can help me build a sophisticated middleware system to manage various API integrations. Key Requirements: - Handling a variety of API integrations: This includes those from social media (e.g., Facebook, Twitter), payment gateways (e.g., PayPal, Stripe), as well as third-party APIs (e.g., Google Maps, Weather). Your experience with these APIs will be invaluable. - Real-time data synchronization: The middleware must be designed to support real-time data synchronization. It is essential that the developer has a proven track record in developing real-time systems. - Advanced error handling and logging: I expect the middleware to provide detailed error diagnostics and to be integrable with monitoring tools. Experience with creating such robust error handling systems will be highly valued. If you are confident in your node.js skills, have a good amount of experience with API integration, real-time systems, and advanced error handling, I'd love to hear from you.
