Curriculum Vitae: Kalle Hallivuori

Suomeksi / In English

I am an experienced IT professional with good common sense. My aim is to do things right - with regard to the context and costs. Life-long commitment to computer science, years of work and studies have helped me to reach a level where learning new skills is a part of my everyday life. I am able to creatively apply several theoretical models to all phases of IT work, from initial identification of problems to planning and implementing solutions. I know how to make things tangible when communicating in a team and with customers as well as in teaching and documentation.
