FAQ
Do I need to provide my own API keys?
Yes, for OpenAI or third-party integrations, you will need to provide your API keys. I will guide you on how to set them up securely if needed.
Do I need to use OpenAI exclusively?
No! I can integrate a wide range of LLMs, including Anthropic (Claude), Google Gemini, DeepSeek, Llama, or open-source models via Groq, Together AI, or Hugging Face, depending on your budget and needs.
Can you work with my existing codebase?
Absolutely. I can work with your existing React, Next.js, Python, or Node.js repositories. Just provide access via GitHub/GitLab, and I will integrate the feature or fix the bug without breaking your current layout.
What if I don't have technical knowledge?
No problem at all! I handle all the technical heavy lifting. I will explain everything in simple terms, set up the solution, and provide easy-to-follow instructions so you can use it right away.
Do you offer support after delivery?
Yes, all packages include post-delivery support to ensure everything is running smoothly and to fix any minor issues related to the original scope.
