FAQ
Will my project be outsourced to an agency or third party?
No. I am a professional AI & Backend Engineer and personally handle the design, development, testing, and delivery of every chatbot. No agencies. No outsourcing.
What technologies do you use to build AI chatbots?
I primarily use Python, Rasa Open Source, FastAPI, NLP, and Machine Learning. The tech stack is chosen based on your use case, scalability needs, and budget.

Yes. All chatbots are designed with production scalability in mind, including clean architecture, backend APIs, logging, and deployment readiness.
Can you integrate the chatbot with my database or existing systems?
Absolutely. I can integrate chatbots with databases, APIs, CRMs, dashboards, or internal tools as needed.
Will I receive the full source code and documentation?
Yes. You receive full ownership of the source code along with clear setup and usage documentation.
Should I message you before placing an order?
Yes, messaging first is recommended. It helps clarify requirements and ensures I suggest the best architecture and package for your use case.
