About
I like turning my own ideas into small, useful products: iOS and macOS apps, real estate tools, and websites people actually use. Most projects start with a concrete everyday problem, then I keep refining the details until the flow feels clear, fast, and easy to find.

Property tips
EUR 1,500Referral fee
Know a property before it goes online?
I am looking for smaller residential units, apartments, houses, and small multi-family homes in Mainz, Wiesbaden, and Rheinhessen that are not publicly listed yet. Private intent to sell, vacancy, inheritance, renovation needs, or an upcoming move are especially relevant.
The fee is only due if the property was not already known to me, your tip caused the purchase, and the purchase was notarized.The cleanest way is to forward my contact details to the owner. Please only share third-party contact data if that person has agreed.
