Reading and writing have been David Nivala's interests for many years. He holds qualifications in both technical and financial areas. During his life, he has worked as a machinery operator, a mechanical engineer, a financial accountant and he has held many managerial positions in both the profit and not for profit sectors. His current interests are playing and listening to music, woodworking, hiking and writing. There are never enough hours in a week to do all the things he would like to do. Johan Jokobi is a figment of his imagination and David hopes to continue writing about him for some time. He is supported by his family and friends in this activity.
