FAQ
What do you need from me to get started?
I will need a summary of your AI SaaS concept, a list of required features (such as user roles or custom prompts), and your target wireframes if you have them.
What technologies do you use to build AI SaaS apps?
For the frontend and user interface, I use Next.js, React, and Tailwind CSS. The backend systems are built using Node.js or Python, connected to secure databases like PostgreSQL or Firebase, along with Pinecone vector databases for handling memory pipelines.
Can you build both web and mobile versions?
Yes, absolutely. Under the Premium tier, I build a completely synchronized ecosystem. This means you launch a responsive Next.js web app alongside a native mobile app (iOS & Android) that utilizes the same database backend, Stripe subscription data, and AI prompt architecture.
Will you also handle UI/UX design?
Yes, I provide clean, modern, responsive UI/UX using Figma before development starts — so you know exactly how your SaaS will look and feel before it’s built.
