The problem

You need an app to support a process, a product, or your field teams, whether that is a web app, a mobile app, or an internal tool, but quotes are either sky-high or suspiciously cheap. Cheap apps come with scope creep, unreliable code, and a rewrite six months later. For business-critical operations, reliability is not optional.

What you get

My background, and a note on price: I am an engineer with 20 years of industrial experience. I have built web and mobile apps with React, .NET MAUI, and Xamarin, desktop business software with PyQt/Qt6, and cloud back ends on AWS. I do not try to be the cheapest option; I would rather build something reliable that holds up over the life of the app.

How we work together

  1. Free audit: We define the smallest app that delivers real value.
  2. Scoped plan: Fixed features, timeline, and a flat fee or milestones.
  3. Build the MVP: Web, mobile, or desktop, with the back end and integrations you need.
  4. Ship & iterate: Release to users, then improve based on real feedback.

Pricing

From €5,000 for a rapid MVP, as a flat fee or milestones. I never sell "low cost" apps. That path leads to scope creep and rewrites. Instead you pay for speed and reliability. Final pricing depends on features and integrations, confirmed in the free audit.

FAQ

How fast can you build an app MVP?

For mobile, building cross-platform with React Native, Flutter, or .NET MAUI ships one codebase to both Android and iOS; for web, I build directly in React or Vue. Either way a focused MVP typically takes a few weeks depending on scope, confirmed after a free audit.

Do you build web apps or mobile apps?

Both, plus desktop. I build web apps in React or Vue, cross-platform mobile apps that run on Android and iOS from one codebase, and desktop tools in PyQt/Qt6 when that fits best.

How much does an app cost?

A rapid MVP starts from €5,000. Pricing can be a flat fee or milestone-based. The final number depends on features, integrations, and whether the app connects to industrial systems or back-end services.

Can the app connect to our industrial systems or back end?

Yes. I build the back end too, with Python, FastAPI, and databases, and I have connected software to industrial PLCs and cloud services, so your app can integrate with existing systems securely.
