Your app deserves better than neglect.
Forget sleepless nights over store updates and security vulnerabilities. You focus on your core business. Your app runs reliably in the background.

Sound familiar?
Each of these problems costs you real money, user trust, and valuable time. Time you could invest in growing your business.
Store rejection after an update
If your app gets removed from the store, you lose your most important distribution channel overnight. Along with revenue and customer trust.
Bugs keep piling up
Every unresolved bug costs you users, and every bad review scares away potential new customers. This directly impacts your revenue.
Performance is declining
When your app stutters and loads slowly, you lose users to the competition. Your customers expect a fast, smooth experience. Every single time.
Security vulnerabilities stay open
A single security breach can ruin your reputation and cost you dearly. It is not just a technical risk, but also a data-protection risk. Your customers' trust is not something you can afford to risk.
Does this sound familiar?
Is app maintenance right for you?
Your app is live, but nobody's looking after it
The original developer is no longer available or your team has other priorities. I take over the ongoing care of your app.
You've been flagged by Apple or Google
I'll get your app back into compliance quickly. Whether it's privacy manifests, target SDK updates, or new store guidelines.
Your ratings are going downhill
Bugs, crashes, and performance issues are frustrating your users. I systematically stabilize your app.
You don't have your own development team
As an external senior developer, I'm your dedicated point of contact. Without the overhead of an agency.
Sounds like your situation?
How the collaboration works
App analysis
I thoroughly review your app: code quality, dependencies, store compliance, performance, security, and your test coverage. You receive a clear status report.
Maintenance plan
Based on the analysis, I create a prioritized plan: what needs immediate attention, what can wait, and what I recommend long-term.
Ongoing support
Regular updates, bug fixes, and optimizations. I keep you informed with status reports. Transparent and without surprises.
Proactive monitoring
I track store changes, OS updates, and security advisories. I resolve issues before your users even notice them.

Why work with me?
12+ years of hands-on experience
In more than 12 years as a developer, I have worked on apps for komoot, IBM, RTL, and Congstar, among others. For you, that means: less risk, faster solutions, and proven strategies for any situation.
Direct communication
You get fast answers and short communication paths. No detours through a project manager. This saves you time and prevents misunderstandings.
Proactive, not reactive
Issues are resolved before your users even notice them. For you, that means: fewer outages, better ratings, and happier customers.
Predictable costs
You have full cost control with a fixed monthly rate. No guessing, no unpleasant surprises. Your budget stays predictable.
