What You Want (And What I  Offer):  Client Oriented Testing

You and your team build software and you’re looking for someone who can help you with software testing. Preferably one who likes to share his knowledge and who’s ultimate goal is to make himself superfluous. The whole approach to testing depends on what kind of information you need to make your business decisions. Some questions are:

  • Does the software meet given requirements/specifications?
  • What are the risks of releasing (or not releasing) the software?
  • How can we deploy continuously to our production system?

Depending on what exactly you need to know, the strategy, design and execution varies a LOT.
I help you to find the right questions for your business as well as set up a special tailored test approach for your product (or project).

As I wrote in “Testing And The Two Values of Software

Also, I definitely want my clients, as well as their clients, to be happy with the software I help to develop, not only today […].

And I mean it. I do believe great software is possible.

A Selection of Bug Reports

Bug reports are one work product of testers. Here are some links to bugs I reported:

Some Code

Here’s some code I wrote:

It’s a Ruby gem that helps to detect whether or not criteria are met for at least or at most a given number of elements in a collection.


If you prefer that, here’s a more classical view in form of a PDF file.
