FAQ
Do I get the full source code?
Yes! Full source code ownership is included in the Standard and Premium packages. This ensures you own your asset completely. The Basic package is designed for testing backend logic/scripts only.
Can you train the AI on my own PDF/Data?
Absolutely. I specialize in RAG (Retrieval-Augmented Generation) and Fine-Tuning. This allows the AI to answer questions based specifically on your company's documents or database.
Are there hosting costs involved?
Yes. Since we are using third party APIs (like OpenAI) and cloud hosting (like AWS or Vercel), you will need your own accounts. I will help you set these up so you have full control over your billing and usage.
What is "Spec-Driven Development" and why does it matter?
It is a professional engineering approach where we define the exact behavior of the software before writing code. This ensures fewer bugs, faster delivery, and a guarantee that the final product works exactly as required.
