Have a project? Let’s talk about it.

Do you need a modern website, custom software or an AI application, or do you want to automate a workflow?

I am also happy to help with algorithmic trading systems, existing programs or smaller technical adjustments.

Briefly describe your idea or your problem. Together we will work out which solution makes sense.

A few sentences are enough to start.

Process

How we work together

  1. 01

    Discuss the project

    You describe your idea, your problem or the feature you need. Together we clarify the requirements and the scope.

  2. 02

    Planning & quote

    I assess the technical approach, structure the project and discuss the plan, the effort and the costs with you.

  3. 03

    Development

    I build your project — from single features to complete software solutions — and keep you informed about important progress.

  4. 04

    Testing & review

    The solution is tested. We go through the results and any adjustments that are needed.

  5. 05

    Completion & handover

    When the work is done you receive the agreed results and the related files or access, as far as they are part of the agreement.

Does my project have to be big?

No. A bug, a missing feature or a small tool is a normal project. Small, clearly scoped jobs are welcome.

What should I bring to the first conversation?

A few sentences are enough. Helpful, if available: existing source code, screenshots or examples, the systems it has to work with, and deadlines.

Do I get the source code?

Yes, as far as it is part of the agreement: source code, the settings used and documentation, so that you are not dependent on me afterwards.

Does my project need AI?

Only if it helps. I use AI agents as a development tool and I build AI agent systems, but plenty of projects need no AI at all, and I will say so if yours does not.

Can you guarantee that a trading system will be profitable?

No, and nobody honestly can. I can build your rules correctly, enforce your risk limits and test the result under assumptions that are written down rather than hidden.
