Mission Statement

I am a Jack of all trades in technology and I believe in the power of prototyping to evaluate business models.

My mission is to solve hard technical or conceptual problems. Therefore I either build and operate stuff very efficient by myself as a software engineer or work together with startups and entrepreneurs, tackling their technical challenges as a business designer.

If you are interested in my services, hire me!
You are also welcome to just follow / friend me at Facebook, Twitter or LinkedIn because I post quiet some content on those topics.

Zettel v1.0 – Shopping list prototyping as Google Spreadsheet

It’s Saturday. Saturday we do our weekly shopping. Every week one thing bothers me: The supermarket is sorted differently than the shopping list. A constant back and forth – here I saw potential for optimisation.

We always have a backlog of recipes + ingredients that we make regularly. I have now transferred this into Google Drive and provided the ingredients with a supermarket sequence.

So at the end the table can be sorted and printed out according to the order – and the purchase becomes more structured.

That’s just a rapid prototype for now.  I could even make something like an app out of it – but I prefer paper, because otherwise I have to balance the phone + shopping cart + child all the time. But let’s see what else results from the use.

You can find my template here. You can copy it and experiment a bit yourself. Works in this version for the Kaufland in Berlin Gesundbrunnen.

This is what paper v1.0 looks like in action:
