Manager Global Technical Support at AVIRA

Johannes was a very open minded, honest person and easy to work with. I felt impressed by his "get things done attitude" he made sure all of our services in KL Office were up and running even on a tight deadline with his in depth knowledge in networking. I would enjoy to work with him again.

I worked directly under Johannes and I consider myself fortunate to find such a good guide and mentor. He always welcomes new ideas and allowed free and creative thinking. He gave us the free hand to implement our ideas. It has been a really good and enriching experience working with him.

In my time at Avira where Johannes was my manager, I have experienced him as an enabler rather than a controller. In stead of trying to govern top-down an employees daily work, he trusts them in their knowledge and judgement to fulfil the tasks at hand. If you need anything to achieve your job, guidance or just a great guy to talk to, Johannes is there for you without hesitation. Johannes is also especially great at keeping bullshit away from your desk, shielding you from unnecessary discussions and politics so you can focus on the task or problem at hand. These things make Johannes a great guy to work for and allow you to grow to the best of your capabilities!

I had the opportunity of working with Johannes Kresse for three months in Electronic Arts and I only have positive feedback for him. Johannes is a fast learner that rapidly adapts to new realities in order to deliver his work with quality, professionalism and efficiency. He is very analytical, methodical and works extremely well under pressure, either on his own or when being part of a team.

I had several managers during my carrier and I can say that the majority of them were quite good. But none of them has even come up to half of Johannes' level of managing skills. He's a natural. He has modern managing expertise and he knows how to motivate the people under his command like no other. He is an asset to any IT company, he delivers and he is very focused on results.
