Oliver Heeger

But I am a consultant, passionate team leader and full stack web developer with 18 years of experience in the web industry.

I currently work at denkwerk GmbH in cologne, where I spend most of my time crafting and working on awesome projects.

I love what I do! I take great pride in what I do. And I can't do something halfway, three-quarters, nine-tenths. If I'm going to do something, I go all the way.
