Daneel Development is my one-person studio in Uslar, in the Göttingen, Kassel and Northeim region.

Nerd since the '90s.

In the AI era, that pays off: I know what good code looks like, even if I no longer type it myself. My knowledge and experience steer, concept and responsibility stay with me - I use AI as my tool, not as my autopilot.
of Germany. On site or fully remote: where you're based doesn't matter. I love getting creative building exactly what you have in mind. I build custom websites, software and AI solutions for anyone who wants something of their own.
You talk directly to me, and I build what you actually want. Nothing missing. No extra frills you don't need. Short paths, clear communication: first we clarify what's really needed. Only then do I start. That saves everyone involved effort and cost. No over-engineering, no nasty surprises at the end.

Working together during development
Throughout the build, I keep talking with you about what you like, what you do not like and how you want things to work. I incorporate your ideas and wishes as you intend them, so the result matches what you had in mind.
When I take on a project, it becomes my priority. If something does not work or takes longer than planned, my working day gets longer.
Understanding AI and putting it to work
I have followed modern AI since its earliest publicly available offerings, trying new models and tools myself. Over the years, I have learned about their progress, limits and characteristics through hands-on experimentation, comparisons and use in my own projects.
This has given me a deep understanding of how to guide AI and work with it efficiently: what information a model needs, how to break down complex tasks and where its results need closer scrutiny.
I have built my own working environment around Claude Code and Codex. It gives models the relevant project context, tools and clear workflows. Custom instructions, checks and safeguards define how they work. This allows me to apply their capabilities to planning, development and quality assurance.
Client content and credentials do not go into systems that are not intended for them. The same protection your data receives in operation applies during development as well.
Quality in everyday use
For me, quality shows in how well a solution works in everyday use. A website needs to be clear and easy to use across devices. Software should perform its tasks reliably, and an AI feature needs to produce results that can be checked.
I test the implementation against specific tasks and document the results. You know what has been checked, where the limits are and which points remain open.
Handover and continuing independently
Whether it is a website, custom software or an AI integration, we clarify early on what you want to operate, maintain or develop yourself. For a website, that might mean editing text and images; for software, managing data and users; for an AI solution, maintaining its knowledge sources.
You receive a clear introduction and the documentation your solution needs. If your own IT team or another developer will take over, the handover includes source code, technical documentation and the necessary access.
Setup and operation are part of the picture too, whether the solution runs on your devices, your own servers or with a hosting provider. For websites, I also help with domain and email setup. If you would like support after handover, we agree on an arrangement that fits your needs.
