What I do
Mobile engineering is the foundation: architecture, hands-on development and a decade of shipping apps in regulated, high-scale environments. AI is the multiplier on top of it — which is why one senior architect can now deliver what used to need a small team.
I build apps.
Architecture and hands-on development for Android, iOS and cross-platform products — greenfield builds as well as apps that have outgrown their architecture.
I build AI into apps.
Large language models and agents turned into reliable product features — inside real, shipping software, not demos.
I build the systems that build apps.
For teams that want their own pipeline: agent systems that carry work from specification through implementation, review and QA. A separate engagement, not part of every project.
Selected work
Startups, scale-ups, agencies and enterprises across healthcare, fintech, mobility and consumer apps — many of them serving millions of users under hard deadlines and strict regulation.
Case highlights
Built a Gematik- and OWASP-compliant KMP/CMP authentication SDK from scratch for BARMER & AOK — shipped to production in 3 months under a hard regulatory deadline.
As Co-Founder & CTO at recoupling — known from “Die Höhle der Löwen” — I rebuilt the Android architecture from an 85% crash rate into a stable, scalable product, helping secure new funding.
For Star Finanz I led the StarMoney XML → Jetpack Compose migration and implemented SEPA Instant Payments under strict German banking regulation — without disrupting daily banking users.

Most engagements look like this — whether it is a new app, a rescue, or a modernization. Straightforward senior engineering, with AI where it genuinely helps.
The product goal and the constraints: users, platforms, regulation, timeline. If an app already exists, an honest review of its architecture and technical debt.
The decisions that are expensive to reverse later — native or cross-platform, module boundaries, state and data layer, release strategy. This part is mine, not an agent’s.
Hands-on implementation in your codebase and your conventions. AI agents make this step significantly faster — under my architecture and my review.
Tests, code review, store and regulatory requirements, release. Your team gets a codebase they can keep building on — not a black box.
AI changes how fast steps 3 and 4 go. It does not change who is accountable for step 2.
A separate offering
This is a distinct service — not the way every mobile project runs. For teams that want it, I build the agent systems that carry a ticket from specification to a production release inside their own codebase, with the same quality gates a senior engineer would set by hand.
Human in the Loop
Nothing ships without your sign-off.
Human in the Loop
The agents do the heavy lifting — but every plan and release passes through your team. Nothing ships without review and sign-off.
You set the goal: requirements, constraints and acceptance criteria.
The agent breaks the work into tasks and proposes an approach for your team to approve.
It writes the code across your codebase, following your conventions.
Tests, review agents and guardrails run on every change — failures loop straight back to Build.
Once checks pass and you approve, the change goes to production.
Quality, built into every step
AI Software Builder
Complete AI software builders that run a whole delivery flow: you send a feature request to a bot — on Telegram, for example. One agent breaks it into GitHub issues, the next implements them, another reviews the code, and the finished result comes back to you for approval. No large dev budget, no months of waiting.

What that means for you
From request to review in hours — not multi-week sprints.
Every change is tested and reviewed before it ever reaches you.
Agents work around the clock — without a full dev team’s budget.
Ship apps that used to demand heavy funding and months of work.
Two different things: mobile products I build for you — and delivery systems that build software for your team.
About me
Mobile Software Architect & AI-Native Engineer
A software engineer with 15 years in tech and over a decade specialising in mobile — native Android, Kotlin, Kotlin Multiplatform and Flutter — for products used by millions.
Most of that happened in some of Germany’s most demanding, regulated environments — healthcare and fintech — for clients like BARMER, AOK, Deutsche Bahn, Die Techniker and Star Finanz. I also co-founded recoupling, an app with 300,000+ users known from the TV show “Die Höhle der Löwen”, where I’m CTO.
Over the last years I rebuilt my own engineering process around AI agents and agentic delivery. Not as a replacement for architecture and review, but as a multiplier on top of them — held to the same quality and security standards I learned building mission-critical apps.
