FAQ
What do you need to get started?
To get started, I’ll need your project idea, business goals, required features, and any design or reference examples. If your project involves AI (RAG/chatbot), access to your data source or content is also required.
Which AI models do you use?
I work with leading AI models like OpenAI (GPT), Claude, and Gemini, depending on your project needs. I can also recommend the best option based on performance and cost.
Is AI usage free?
No, AI APIs are token-based and paid services. For development, I use my own credits, but for live deployment, you will need to connect your own billing account. The cost is usually low (around $5 can last 2–3 months depending on usage).
Can you integrate AI with my existing website or system?
Yes, I can integrate AI chatbots or automation systems into your existing website, CRM, or internal tools using APIs or custom backend solutions.
What is RAG and why is it useful?
RAG (Retrieval-Augmented Generation) allows the AI to use your own data (documents, website, database) to give accurate and context-aware responses. It is ideal for business chatbots and internal tools.
Will my AI solution be scalable?
Yes, all solutions are built with scalability and performance in mind, so your system can handle more users and data as your business grows.
Do you provide deployment and hosting support?
Yes, I provide full deployment support on platforms like Vercel, AWS, DigitalOcean, and can also guide you on domain and server setup.
Can you customize the UI/UX design?
Absolutely. I create modern, responsive, and user-friendly interfaces tailored to your brand and business requirements.
Do you offer ongoing support after delivery?
Yes, I offer support after delivery for bug fixes and minor updates. For long-term maintenance or upgrades, we can discuss a separate support plan.
Should I contact you before placing an order?
Yes, I highly recommend messaging me first to discuss your requirements. This helps ensure the best solution and avoids any confusion.
