FAQ
Do you build the whole app or just the AI part?
The whole product, frontend, backend, database and the AI logic that ties it together, not just a script wrapped around an API.
Which AI models do you work with?
Mostly OpenAI and Claude, plus open source models when a client needs everything self hosted. I pick whichever fits the budget and the data sensitivity, not one tool for everything.
Can you work with my existing codebase or app?
Yes, send access during the discovery call and I will tell you honestly whether it is a clean fit for AI features or needs rework first.
What if I am not sure what I need yet?
That is exactly what the Basic package covers, we figure out the real scope and the right approach together before any development starts.
How long does a typical project take?
Standard builds run about three weeks, Premium builds with multiple integrations run about six to seven weeks. Exact timeline depends on scope, confirmed after the discovery call.
What do you need from me to get started?
A short description of the problem you want solved, access to any existing systems or data, and answers in the requirements form once the order starts.
Do you sign NDAs or handle sensitive data?
Yes, I sign NDAs on request and I am used to working with private business data, healthcare information and financial records under proper handling.
Can the AI connect to my existing website, CRM or database?
Yes, connecting to existing systems through APIs is a normal part of the build, whether that is a CRM, a payment processor or your own database.
What happens if my project needs more hours than the package?
I will tell you before going over, not after, and we agree on extra hours or a scope cut together so there are no surprise costs.
Do you offer ongoing support after launch?
Yes, Standard includes 14 days of support after delivery and Premium includes 30 days, and I also offer a monthly retainer for ongoing maintenance if needed.
