About Theo Den Hollander

Responsible for the entire technical backbone i.e., architecture, the software product line, to ensure consistency, quality and productivity in it.From our DISC personality test (https://www.123test.com/disc-personality-test/), my personality profile is frequently called ‘The Results-Oriented‘:"You are individualistic, demanding and persistent. You seek out challenging situations and are responsive to competition. You should be able to handle the daily stresses and pressures of work and life. However, when really pushed, you may become rather irritable and fault-finding. People see you as a 'take charge' sort of person who is self-confident and strives for results."From our extended Jung personality type test (https://www.123test.com/jung-personality-test/), you can characterize me as Introvert-iNtuitive-Feeler-Judger (INFJ) personality type: "Developer" or "Author" and it is shared by approximately 1% of the population. An INFJ on a team: Encourages harmony and gets everyone to contribute. Brings enthusiasm and forward thinking to a project. Provides big picture overviews and in-depth synopsis of situations and problems.INFJ leadership style: Becomes an advocate for others and their talents when leading. Inspires others to follow through his/her enthusiasm and faith. Can become a champion for ideas and causes.INFJ Communication Style: energy and excitement inside self. Prefers to think before replying and needs to be drawn out. Prefers written reports over talking in person. Prefers language that is global and metaphoric, instead of precise and plain.Problem solving style (INFJ):Is comfortable with complicated situations. Perceives the abstract relationships between subjects first, then fits all the pieces together. Looks first at the big picture, then contemplates people. Next applies logic and finally turns to the facts. Asks if the current problem is similar to a previous event. Wants to know what all the possibilities and alternative solutions are to a problem.
