FAQ
Which AI models can you integrate?
OpenAI (GPT), Claude and Gemini. I help you pick the right model for quality, speed and cost, and set it up so you can switch later.
Can you work with my existing codebase?
Yes. I work with React, Next.js, Node.js, NestJS and Python apps. I review your code first and add AI without breaking what already works.
Can the AI use my own data?
Yes. I can connect it to your database, documents or APIs so answers and actions are based on your real business data.
Who pays for API usage?
You use your own OpenAI, Claude or Gemini account, so you keep full control of keys and costs. I add usage limits to keep spending predictable.
What if something breaks later?
You get 30 days of bug-fix support after delivery, plus clean, documented code that any developer can maintain.
