Frequently Asked Questions
Quick answers to the most important questions
After the initial meeting, I create a detailed proposal with a fixed price. After acceptance and a 25% deposit, development begins in milestone-based steps. You receive regular updates and can provide feedback at any time.
A simple website takes 2-4 weeks, business websites 3-6 weeks, complex web apps 8-12 weeks. The exact duration depends on the scope and your individual requirements.
The price depends on your individual requirements and desired features. You receive a transparent fixed-price proposal upfront with no hidden costs – and you don't need to pay agency prices for a professional result. Get in touch for a free consultation – I'm happy to advise you.
Yes! I offer both custom partial solutions for existing Shopify stores or WordPress sites (e.g. custom sections, plugins, components) as well as brand new websites and shops – whichever makes the most sense for your project.
Yes! Every project includes 24 months of basic support: limited to minor project-related tasks: basic usage questions, small text/image changes to existing content of up to 30 minutes per month (non-accumulating) and bug fixes under warranty. Anything larger – e.g. new pages or sections, new features, design changes, technical updates, hosting, domain and licences – is not included and is billed separately. After that, support can optionally be continued for €199 per month incl. VAT (fixed 24-month term). Additional services are available at fair hourly rates; larger feature extensions are calculated as a separate project.
Yes! Federal and state programmes across Germany offer attractive funding for digitalisation projects, depending on your region. Important: the application usually has to be submitted BEFORE the project starts. I'm happy to advise you on the options and support the application process.
I use AI tools for routine tasks (boilerplate code, documentation), but make all strategic decisions myself. Every piece of code is reviewed, tested, and optimized by me. You don't get a generic AI solution, but well-thought-out software with human expertise.
Frontend: React, Next.js, TypeScript, Tailwind CSS. Backend: Node.js, REST APIs, authentication & caching. Databases: PostgreSQL, MySQL, Supabase, Prisma. Shop systems: Shopify Liquid, WooCommerce, WordPress. The technology is always chosen to fit your project.
Yes – on-site appointments are available all across Germany. The consultation itself is free; only a one-time travel flat rate (incl. VAT) applies based on distance: up to 150 km €69, over 150 km €119, over 300 km €179. Remote video calls are of course free of charge.
