Yhteenveto

I am a technically oriented person, with a drive for making data
valuable for the Business. I like the double aspect of the data
warehouse environments, the fact that data needs to be handled in
one way for the environments to perform well, and at the end, having
the Business requirements as the ultimate goal.

I'm highly motivated seing the solution having a beneficial outcome for
the Business side aswell as seing a solution that works well when
delivered to the maintenance department after the project work has
finished.

I have worked In most areas of the development lifecycle, and tend to
be the one working with the business side, working on data analysis
and data investigation, at the end of the project.

Over the 20 years I've been in the industry, I have gained a lot of
experience in many aspects. Learning the vital need for respect of
everyone involved, and the importance for clear communications and
quality throughout the full lifecycle. Time has also showed me, that
different people and units, sees things differently, and to always have
that in mind.
