I will build rest API endpoints using nodejs express and mongodb

Scope review, REST API development, MongoDB setup, authentication if included in your package, endpoint testing, and handover notes.

Frontend UI, mobile app screens, paid hosting, domain setup, paid API subscriptions, and large third-party integrations unless added to scope.

You should provide project requirements, existing code if available, database details, API documentation for integrations, and deployment access if deployment is included.

Only if your API connects with paid third-party APIs or AI services. Those costs are billed directly by the provider.

MongoDB Atlas and many hosting platforms have free tiers for small projects. Larger apps may need paid hosting depending on traffic and usage.

Basic includes 1 revision, Standard includes 2 revisions, and Premium includes 3 revisions for the agreed scope.

Security is a priority. I implement industry-standard practices, including secure API calls, Firebase authentication, and privacy rules in Bubble to ensure user data is protected.

First we confirm endpoints, data models, auth rules, and expected responses. Then I build, test, document, and hand over the API.

Yes. Premium supports custom auth, role permissions, third-party APIs, webhooks, logging, deployment, and scalable backend structure.

Yes. Monthly backend retainers are available for fixes, monitoring, endpoint changes, and continuous feature development.
