FAQ
Is my company data secure when you build the AI agent?
Absolutely. I build custom RAG (Retrieval-Augmented Generation) architectures. Your proprietary data remains within your secure database or cloud environment. I ensure your private company data is never used to train public models.
Do I need to pay for the OpenAI/Gemini API separately?
Yes, you will need to provide your own API keys for the deployment. You will be billed directly by OpenAI, Google, or Anthropic based on your actual usage. I write highly optimized code to minimize token consumption and keep your operating costs low.
Do you use no-code tools or write custom code?
I write custom, production-ready code (Python, Next.js, Node.js). This ensures your AI architecture is fully scalable, completely owned by you, and not restricted by the limitations or monthly fees of third-party no-code platforms.
