FAQ
What do you need from me to get started?
To begin, I need a clear project brief outlining your goals, target audience, and a list of required features for your AI website, SaaS, or chatbot. Any design mockups, brand guidelines, or examples of apps you like are also extremely helpful. The more detail you provide, the better!
What is your development process like?
My process is transparent. We start with discovery and planning. Then, I move to development, providing regular updates. You'll review the work for any revisions before the final deployment. This ensures the final product perfectly meets your vision.
Which AI models or APIs do you work with?
I integrate a wide range of AI models, including OpenAI's GPT series for advanced chatbots, LangChain for complex AI workflows, and other third-party services. We will select the best technology to power your project's specific needs
What if my project is more complex than your packages?
My packages are starting points. If your AI website or SaaS platform requires more advanced features, please send me a message with your project details. I will create a custom offer tailored specifically to your unique requirements.
Do you provide support after the project is delivered?
Yes! All of my packages include 2 months of free post-launch support to fix any bugs or technical issues. For long-term maintenance or adding new features, we can discuss an ongoing support plan that fits your needs.
Will I own the full source code for the project?
Absolutely. Upon project completion and final payment, you will receive the full source code for your application. You will have 100% ownership of the intellectual property.
Can you integrate AI features into my existing website?
Yes, in most cases. I can analyze your current website's architecture and integrate new AI features like an intelligent chatbot or a recommendation engine. Please contact me with details about your site so I can assess the project's feasibility.
Do your packages include a domain name and web hosting?
My packages cover the application's design and development. Domain and hosting are separate costs you will need to purchase. However, I am happy to provide recommendations and assist with deploying your project to your chosen hosting provider.
