FAQ
I don't know anything technical — can I still work with you?
I don't know anything technical — can I still work with you?I don't know anything technical — can I still work with you?
What do you need from me to get started?
Your documents, website content, or data the bot should learn from, a clear idea of what you want it to do, and API keys for OpenAI or Claude (I can walk you through getting these if you don't have them yet).
Will there be any ongoing costs after delivery?
Possibly — things like OpenAI/Claude API usage and hosting (Streamlit Cloud, Vercel, etc.) are billed separately by those providers, not by me. I'll give you a clear cost estimate before we start so there are no surprises.
Can I make changes myself after delivery?
Yes. You'll get the full source code, and I'll include simple instructions so you or your team can update documents, tweak settings, or make small changes without needing me every time.
Do you work across different time zones?
Yes, I'm flexible and happy to accommodate your schedule for calls or updates.
I already have a chatbot or RAG app — can you improve it instead of building from scratch?
Yes. I can review what you have, fix issues, or extend it with better retrieval, an agent layer, or a cleaner UI.
What if I'm not happy with the result?
We'll work through revisions together until it matches what you need — my goal is a result you're actually satisfied with, not just a delivery I can mark done.
