About

Hi, I make videos about software development related topics like Java, web development etc. Occassionally I'll drop a video or two about career related issues too. Oh, I also run the tutorial website http://jenkov.com . I try to cover each topic in reasonable depth. My own experience has been, that the deeper my understanding of topics within software development is - the better and faster a developer I become. I started programming around 1987 (around age 12) on the C128 - in C128 Basic - then on the Amiga 500 in AMOS and Assembler, then later PC and C. I started working with software as job from 1998 as web dev, and from 1999 as Java + web dev, so I've been in the game a long time :-) From around 2000 and forward I have mostly been working as a freelance, onsite consultant with Java, web and distributed systems deelopment. I love being self employed - but it's a lot of work.
