Fullstack Development
Custom software development
that fits you.
Custom applications that adapt to your workflows instead of the other way around. From a single web app to a complete platform.

- Test the API contract
- Prepare the build
When custom?
Software should solve problems, not create new ones
Standard software is often a good starting point. Custom development makes sense when specific workflows, integrations or multiple sites otherwise require recurring manual work. We first check what existing systems can already do.
I develop software that does exactly what you need. For that I use technologies that will still be maintainable in five years, and write the code so other developers can find their way around it quickly.
Applications
What I develop
From the first idea to the finished application, tailored to your requirements
Web Applications
Modern single-page applications and Progressive Web Apps. Responsive, fast and usable on all devices, without app store hurdles.
Mobile & Desktop
Cross-platform applications with React Native or Electron. One codebase for iOS, Android, Windows and Mac.
Backend & APIs
Scalable server applications with .NET or Node.js. Secure REST and GraphQL APIs for your frontends and partner integrations.
Integrations
Connection to existing systems like ERP, CRM or industry software. I connect your applications with each other.
Technologies
What I work with
The choice follows your existing systems, requirements and maintenance needs. Not every project needs the entire stack.
TypeScript / React
Type-safe development for frontend and backend
.NET / C#
Enterprise-ready backend development
PostgreSQL / SQL Server
Relational databases for your business data
Git / CI/CD
Version control and automated deployments
Next.js / Node.js
Modern web frameworks for rapid development
Docker / Cloud
Containerization and cloud deployments
In use
From administration to AI integration.
AI assistants for routine tasks
I integrate AI that evaluates inputs and creates suggestions or drafts. That takes manual routine steps out of your daily work.
Analytics and reports
Standardized data capture and central evaluation. Comparable metrics at a glance, across all areas.
Central control
One interface for multiple locations or areas. Manage and roll out settings, content and schedules centrally.
AI email agent
Classify incoming messages, draft replies and route complex cases to people. We define which replies may be sent automatically based on risk and quality.
Working together
A clear path to everyday use.
Understand
Precisely capture your requirements and goals
Plan
Technical design and scheduling
Implement
Iterative development with regular feedback
Deliver
Documentation, training and support
Before we begin
Good questions. Clear answers.
What does custom software cost?
It depends on the scope. Depending on the project I work with an hourly rate or a fixed price. After the free initial call you receive a concrete quote.
How long does a software project take?
Small tools are often done in a few weeks, larger platforms take several months. I work iteratively, so you see intermediate results early.
Can you extend existing software?
Yes. I also take over third-party code for bug fixes, extensions or ongoing maintenance.
Is there support after go-live?
Yes, optionally with maintenance and further development.
