Contracting or project partner. I build what your team can carry forward.
Contracting
In your team, we build performant software together — I coach, document, and ensure a clean handoff.
Project partner
I deliver end to end — from architecture to production, fully documented and handoff-ready.
Custom web applications — dashboards, portals, internal tools, or customer-facing platforms.
Whether it's a customer dashboard, an internal tool, or a data-driven portal — I build web applications tailored to your business. React, Next.js, and TypeScript on the frontend, solid architecture on the backend. Responsive, performant, maintainable. No off-the-shelf templates — software that fits your processes.
Performant APIs, microservices, and cloud infrastructure — the foundation for scalable products.
Great products need a strong backend. I design and build REST and GraphQL APIs that are well-documented and easy to integrate. Node.js, Java/Spring, or Hono — depending on requirements. Plus cloud infrastructure on AWS, GCP, or Vercel, CI/CD pipelines, and database design with PostgreSQL or MongoDB.
From idea to App Store — native-quality apps from a single React Native codebase.
I build cross-platform mobile apps with React Native and Expo. One codebase, two stores. My own product Baller Manager runs on iOS, Android, and Web — proof that this stack delivers real, production-quality apps. Fast iteration cycles, over-the-air updates, and shared logic with your web platform.
From tech stack to launch: scalable platforms built for real users from day one.
I don't just pick a tech stack and start coding. I work with you to understand your users, design the right architecture, and build a platform that performs from day one. Secure payments, scalable infrastructure, and a frontend that converts — everything you need to compete.
I turn your AI idea into a working prototype — validate fast, invest smart.
Not every AI idea needs a million-dollar budget to prove its worth. I build focused machine-learning prototypes that test your hypothesis with real data. From analysis and model selection to a working proof of concept — you get the clarity to decide whether to scale, pivot, or move on. No guesswork, no wasted budget.
I upgrade your legacy systems incrementally without disrupting your business.
Your legacy system works, but it's holding you back. I modernise applications incrementally: monoliths become micro-frontends, outdated frameworks give way to React and Next.js, manual deploys turn into CI/CD pipelines. You keep running while I rebuild — no big-bang migrations, no downtime surprises.
CI/CD pipelines, infrastructure as code, and automated workflows — so your team ships faster and safer.
Manual deploys, missing tests, and fragile infrastructure cost time and sanity. I set up CI/CD pipelines, automate build, test, and deployment processes, and bring infrastructure as code to your project. GitHub Actions, Docker, AWS, GCP, or Vercel — depending on your stack. The result: your team ships faster, safer, and with less manual effort.

FAQ/*
What technologies do you use?
My core stack includes React, Next.js, TypeScript, and Node.js. For mobile apps I use React Native with Expo. Depending on the project, I also work with Vue, Java/Spring, TanStack libraries, Tailwind CSS, and various cloud services (AWS, GCP, Vercel).
How long does a typical project take?
It depends on scope. An MVP or proof of concept can be ready in 4–8 weeks. Larger SaaS platforms or modernization projects run iteratively over several months.
Do you work alone?
I'm your single point of contact on every project. Depending on scope and requirements, I bring in experienced partners from my network — so you get specialist quality without the agency overhead.
Do you work with international clients?
Yes. I work remotely with teams and clients worldwide. Communication in German and English is standard.
What does the process look like?
I work in short iterations: requirements analysis, planning, development, incremental deployment, and review. This gives you early results and the ability to provide feedback at any time.
