Kim Berg Hansen is a developer from Middelfart in Denmark. He almost coincidentally discovered a talent for computer programming – unlike his first interest, electronics, where his soldered projects often failed. After that experience he progressed from Commodore Basic on VIC-20 over Modula-2 and C to Oracle SQL and PL/SQL, with which he now has worked extensively since year 2000. His professional passion is working with data, utilizing the SQL language to the fullest to achieve high performance.Kim shares his knowledge in the book "Practical Oracle SQL", by blogging and presenting at various OUG conferences, and creating quizzes for the Oracle Dev Gym. His motivation is when peers go "now I understand" after his explanations, or when end users "can't live without" his application coding. He is certified Oracle OCE in SQL and awarded Oracle ACE Director. Outside the coding world Kim is married, loves to cook, and is a card-carrying member of Danish Beer Enthusiasts.
