FAQ
Can you build a new backend or work on my existing API?
Yes, both. I can build backend APIs with Node.js or FastAPI, add integrations to your existing app, or fix API issues. Send me your requirements or current problem so I can recommend the right package.
What is the difference between API development and API integration?
API development means building endpoints for your app, such as login or data management. API integration connects your app to another service, such as Stripe, OpenAI or a CRM. This gig covers both.
Do you offer Stripe and payment gateway integration?
Yes. Standard can cover one-time Stripe Checkout with a verified payment webhook as its included integration. Premium includes one Stripe subscription plan and payment webhooks. Other gateways or more complex billing need a custom quote.
Can you integrate AI chatbots and automation workflows?
Yes. I can connect OpenAI GPT or Claude to your backend for chat, content generation, summarization or automation. Premium includes one agreed AI workflow. RAG, multi-agent systems and larger automation projects are quoted separately.
What counts as an endpoint or an integration?
An endpoint is one API operation, such as creating or retrieving a record. Different operations on the same URL count separately. An integration covers one agreed workflow with one external service. We’ll confirm the scope before you order.
Which package should I choose?
Basic covers up to 3 simple endpoints OR one simple external API integration. Standard covers up to 8 endpoints, authentication, a database and one integration. Premium covers up to 15 endpoints, user roles, one AI feature, Stripe subscriptions and deployment.
Will I receive source code, documentation and deployment?
All packages include source code, relevant code comments, API documentation and testing of the agreed workflows. Deployment to one server is included in Premium and available through a custom offer for other packages. Hosting and paid API usage are separate.
What do you need before starting, and what do revisions cover?
Send your requirements and any relevant API documentation or existing code. We’ll arrange access when needed. Revisions cover adjustments to the agreed work; additional endpoints, new features or extra integrations require a separate quote.
