Native speaker




Kolmar is very much a self-starter and life long learner. He goes out of his way to comprehend things that aren’t readily available on the job. When we look for engineers we look for people who can solve problems, and Kolmar did this on both technical and business levels within our organization. Kolmar served as a mentor to more junior engineers, showing them best practices. He ingratiated himself with leadership by taking on tasks that other people avoided. His sense of humor diffuses tense situations and he’s very approachable.
