Make an API usable by AI
Connect an existing API through MCP so an AI assistant can read data or call functions. Start with one clearly defined use case.

Web applications, dashboards & AI.
I have been developing and modernising software for more than 20 years. My focus is web applications, data visualisation and AI integration.
I am currently exploring self-employment and would like to speak with small software teams, agencies and businesses about concrete projects with a clear scope.

Possible first projects
Already have an application, an API or a data source? These three starting points fit my experience.
Turn data into a dashboard
Connect a data source and bring key metrics, filters or trends together in a useful web view.
VSX PulseExtend existing software
Add a specific feature, investigate a bottleneck or modernise part of an established application. First, we clarify scope and dependencies.
My experiencePersonal projects
I developed and operate these applications myself. These personal projects demonstrate my approach and technical experience.
MCP Werk
Hosted MCP access to German public data, with tools for multiple data sources, authentication and access limits.

Questions about possible projects
Existing technology, AI integration and collaboration: a few answers before our first conversation.
- Can existing applications be extended?
- Yes, existing software is one of my areas of focus. I work with .NET, C# and Vue and have experience with API integrations, data migrations and modernisation. Before a possible project, we discuss the existing technology, dependencies and a manageable first step.
- How can AI assistants use an existing API?
- The Model Context Protocol (MCP) can expose selected data and API functions as tools for AI assistants. MCP Werk demonstrates this with public data sources. For another system, we first need to clarify access rights, authentication and the specific use case.
- Can we discuss a project outside Hannover?
- Yes, I am based in Hannover and also connect remotely. A short email about your application or data source and the desired result is enough to start a conversation. Scope and a possible timeframe are discussed individually.
What problem would you like to solve?
Do you have an application, an API or data you would like to do more with? Send me a few lines. We can first explore, without commitment, whether the project could be a good fit technically and in terms of timing.
Describe your project
A few lines about the problem, existing system and desired result are enough.
Explore the fit
In a non-binding conversation, we discuss scope, technical questions and a possible timeframe.
Agree the next step
Any engagement and implementation would be agreed after the formal requirements have been clarified.
Email
The link opens your email app with a short template. You can also copy the address. A timeframe and budget range are helpful, but optional.
Current status: I am exploring self-employment and collecting non-binding project enquiries. I have not yet registered a self-employed business or freelance activity.
