FAQ
Questions I often get
Do you only work with Next.js and Supabase?
No. I have shipped production systems in .NET, Java, Node.js, React, Angular, Vue and Blazor, on AWS, Azure, GCP and on-premise. I pick the stack that fits your team and infrastructure.
Can AI run without sending our data to OpenAI?
Yes. I set up open-source language models on your own servers so no customer or company data leaves your network. For less sensitive use cases, cloud models are often faster to start.
How do fixed prices work?
After a free discovery call you get a written proposal with scope, timeline and a fixed price. Changes are discussed openly and priced before they are built.
Do you work with clients outside Germany?
Yes. I work remotely with teams in Germany, Europe, the US and Türkiye, in English, German or Turkish. Invoices are issued from Germany.
What happens after launch?
You own all the code. I hand over documentation and can keep your product healthy with a monthly care retainer, cancel anytime.
Have an idea or a process that eats hours every week?
Let's find out in 30 minutes whether AI or a custom product can fix it, and what it would cost.
