Your app can do more. I'll show it how.
Your internal app or business solution needs new features? I extend your existing Android or iOS app with exactly the functionality that speeds up your processes and makes your team's daily work easier.
Sound familiar?
Your app is running. But it no longer covers what your business needs today. Missing features cost your team time and frustration every day.
Your team is working around the app
Important steps still run manually because the app doesn't support them. Your employees fall back on spreadsheets, email, or paper. Losing valuable working time.
Your codebase is slowing you down
You know exactly which feature would move your business forward. But outdated architecture makes every extension expensive and risky. New features take months instead of weeks.
System gaps in daily operations
Your app is an island. Without connections to ERP, inventory management, or other internal systems, data has to be transferred manually. Error-prone and time-consuming.
Processes grow, the app doesn't
Your business has evolved, but your app hasn't kept up. New requirements are solved with workarounds, and every workaround costs you time every day.
Does this sound familiar?
Is feature development right for you?
Your internal app needs new features
The foundation is there, but your business processes have evolved. I build exactly the features that save your team the most time.
You want to connect internal systems
ERP, inventory management, time tracking, or internal APIs: I integrate new interfaces cleanly into your existing app. So data flows automatically instead of being transferred manually.
Your app needs a technical refresh
From XML Views to Jetpack Compose, from UIKit to SwiftUI: I modernize your app step by step. Without rebuilding everything from scratch.
Your team lacks mobile capacity
Your development team is at full capacity or lacks mobile expertise. I step in as a senior developer and deliver the feature. Independently and reliably.
Sounds like your situation?
How feature development works
Feature analysis
I understand your goal, analyze the existing codebase, and assess technical feasibility. You get a realistic evaluation of effort, risks, and architectural decisions.
Concept & fixed price
I create a detailed feature concept with technical specifications, milestones, and a binding fixed price. No surprises.
Iterative development
I develop the feature in short cycles with regular demo builds. You see the progress and can give feedback at any time. Before it's too late.
Integration & rollout
The feature is thoroughly tested, integrated into the existing app, and rolled out through your release process. I support the launch and remain available afterward.
Ready for the first step?
Why work with me?
I think in architecture
Your new features are built to be maintainable and extensible from day one. For you, that means lower follow-up costs, faster future enhancements, and an app that scales with your business.
Direct communication
You talk directly to the developer who writes your code. No detours through project managers or agencies. That saves you time, money, and misunderstandings.
12+ years of real-world experience
Your app benefits from experience across enterprise projects for IBM, consumer apps for RTL, and komoot with 3M+ downloads. You get proven solutions instead of experiments at your expense.
Your existing code is respected
Your existing investment stays protected: No unnecessary refactoring, no vendor lock-in risks. Your code remains yours. You keep full control and independence.
Convinced?
Transparent and fair
Full cost control for your project: Feature development at a fixed price. You know your investment from the start and can plan with confidence. No risk of hidden extra costs.
