Node.js Backend Developer - Third-Party API & Payment Integration

We're a growing beauty and spa brand looking for a solid Node.js developer to help upgrade our booking engine. We’ve already got our frontend built, so your focus will be strictly on the backend integration by building a smooth middleware layer that connects our site to our new booking API. In this role, you’ll tackle multi-location slot availability, guest lookups, and PCI-compliant payment flows. If you’ve worked with appointment APIs before and know how to keep things fast, secure, and reliable, we’d love to work with you. Thanks
