About me
Hi, I’m Christian,a UX / AX Designer and AI Builder. For more than 15 years, I’ve been designing software for complex, data-intensive processes across industries such as banking, mobility, and IIoT.

AI is now an integral part of all my processes – carefully orchestrated and applied where it creates real value, rather than adding more complexity and chaos.

Working together

Fixed production days for design sparring.

Reserve a monthly capacity tailored to your project and needs. Starting from 4 days per month with a minimum commitment of 3 months.

    The fixed weekday

    One day a week that belongs to your product alone: design sparring, fine-tuning, the next feature.

  • Model 028 of 20 working days
    Development mode

    Two days a week: enough to take entire features from sketch into production.

  • Model 03up to 16 of 20 working days
    The partnership

    Half to full capacity. I think and build along as if it were my own product.

    Only for longer-term collaborations: the commitment protects both of us.
