FAQ
What do you need from me to start?
I need your existing codebase or project requirements, AI provider preference, API credentials or access, desired AI functionality, and any UI/design references. If you are starting from scratch, I can help define the technical approach first.
Can you add AI to my existing React or Next.js app?
Yes. I can integrate OpenAI, ChatGPT, or Anthropic Claude into existing React, Next.js, Node.js, or NestJS applications without rebuilding your entire project.
Can you integrate OpenAI and ChatGPT APIs?
Yes. I can integrate OpenAI APIs for AI chat, content generation, structured responses, file-based workflows, automation, and other custom AI features.
Can you integrate Anthropic Claude API?
Yes. I can integrate Claude into your web application and build custom AI workflows using your required prompts, context, business rules, and backend architecture.
Can you build a ChatGPT-style streaming chatbot?
Yes. I can build real-time AI chat experiences with streaming responses, conversation history, custom system prompts, context handling, and a responsive React or Next.js interface.
Is my API key secure?
Yes. API keys should not be exposed in frontend code. I implement API calls through a secure backend or server-side environment and use environment variables for sensitive credentials.
Can you connect AI with my database or APIs?
Yes. I can connect AI features with REST or GraphQL APIs and databases such as MongoDB or PostgreSQL to create customized AI-powered workflows.
How long does an AI integration take?
It depends on the requirements. A simple API integration can be completed quickly, while chatbots, streaming, authentication, database integration, and complex automation may require more time. Please message me before ordering for an accurate estimate.
Do you sign NDAs?
Yes. I can work under an NDA when required. Please discuss the NDA requirements with me before placing the order.
Can you fix or improve an existing AI integration?
Yes. I can troubleshoot API errors, improve prompts, fix streaming issues, optimize backend integration, improve response handling, and help resolve performance or reliability problems.
