A clear product
Understandable user journeys, meaningful states and an interface built around the real use case.
Mobile products
An iOS and Android app that fits the business behind it.
From the first product idea to improving an existing app: user journeys, backend, payments, push, administration and operations are designed as one product.
A strong fit when …
- you need a new app for iOS and Android.
- an existing app is stuck technically or at product level.
- the app, web administration and backend belong together.
- payments, push, login, QR codes or offline workflows are part of the product.
What the result should deliver
A complete system
App, APIs, administration, data and external services work as one connected flow.
A product that can be operated
Releases, diagnostics and continued development are considered from the start.
Technical fit
When the stack is already defined
I frequently use Flutter for cross-platform apps. Backends, APIs and web administration fit the surrounding system, including Node.js, TypeScript and Vue.js where appropriate. Technology follows the product, not the other way around.
Scope
Was ich dabei übernehme
Depending on the starting point, I can own the product end to end or strengthen an existing team where it matters most.
Product & user journeys
Structure requirements, work through critical flows and turn an idea into a product that can be built.
App & system integration
Connect the mobile app, backend, administration, authentication and external services into a dependable system.
Quality & release
Testing, store releases, diagnostics, monitoring and a reliable foundation for future versions.
Continued development
Interpret usage feedback, remove bottlenecks and extend the product in a controlled way.
Collaboration
From idea to an operating product
- 01
Understand
Target users, business model, core journeys and technical constraints are clarified together.
- 02
Focus
We define a sensible first scope, visible quality standards and the most important risks.
- 03
Build
The product is delivered in reviewable stages with regular demos rather than a long black-box phase.
- 04
Operate
Release, observability and the next stages become part of delivery rather than afterthoughts.
