FAQ
Do I need to provide my own Claude API key for my custom AI app?
Yes. To ensure complete control over your usage and data, you will provide your Anthropic Claude API key. I will securely configure it inside server-side environment variables (.env) so it is never exposed on the client side, ensuring maximum security for your custom AI app.
Can you build both an AI web app and an AI mobile app using the same backend?
Absolutely! As an experienced AI developer, I design scalable backend architectures that can serve both your AI web app and AI mobile app simultaneously. This allows cross-platform consistency and saves development time while keeping your Claude API logic centralized.
How do you handle real-time response streaming and token costs?
I implement Server-Sent Events (SSE) or WebSockets to display instant, streaming typewriter outputs for a smooth user experience. Additionally, I optimize prompt engineering, context windows, and structured JSON outputs to keep your Claude API token usage efficient and cost-effective.
Will my custom AI application be secure and production-ready?
Yes. Every custom AI app I deliver includes secure middleware, endpoint rate-limiting, error handling, and clean environment separation. Your API credentials and database interactions are protected against unauthorized access and client-side key exposure.
Do you provide post-delivery support and updates for new Claude models?
Yes! AI models evolve quickly. Whether you need to update to the latest model versions, add new features to your AI web app, or adjust your backend pipelines, I offer ongoing maintenance packages to keep your app running smoothly.
