What Others Say

Professional recommendations from colleagues and team members.

"

Zoltan proved to be one of the most dedicated professionals through his work at LogMeIn. He understands complicated issues even when outside of his direct area of expertise. For Zoltan the job is obviously the most important thing to do. Has an easiness to build interpersonal relations with others. Working at LogMeIn is most challenging, and he thrived. Through the years, we worked on various projects and I was impressed by his manner of doing a great job. Experiencing his quick and sharp mind at the office is most remarkable.

When Zoltan joined our team, he asked a lot of questions. He wanted to learn everything under the sky. He was creating a lot of hope. And he lived up to his expectations. He is a very very fast learner and thinks out of the box. He is not the ordinary associate. He is sharp, intelligent and comes up with bright ideas all the times. He is easy going and a good team player. I am sure he will be a valuable asset to any team. I wish him good luck with his career.
