Overview: On My Work Background

I have over 10 years experience building professional information services for mid- and large-size companies. I offer significant experience in systems analysis, system specification, modelling, design, and programming. I bring to my work a wide-ranging practical experience in application development, a keen mind, and a passion for thinking about interesting things, like your computer problems.

My work covers the full project lifecycle, from early-stage analysis through support and enhancement work. Projects in the last few years include:

On this page you will find a summary of my work over the past 10 years. For a detailed projects resume (or Curriculum Vitae) in English, please contact me by e-mail: see this page for an online contact form. For more information about the range of my skills in software development, please go here.

Work History

I began programming professionally--as a career--in the summer of 1993. I have worked steadily in the field ever since. My clients include companies in insurance, financial services, commercial shipping, retail sales, among others. I have had roles as architect, lead engineer, module owner, or just "one of them". I am glad to put the gloves on and push hard to get the ball rolling. And if the ball rolls down the hill again, well, I just start from the bottom and push it back up.

I have also led small teams in development efforts, and carried out extensive mentoring for new team members and programmers.

Most of my work the last few years has been oriented towards the Internet, for companies interested in an Application Service Provider hosted environment. I also have experience in internal/departmental systems.

I am currently based in Berlin, Germany.

I have written more about my skills in my work. Please take a look at it. My full resume (CV) is available on request. Just contact me and I'll send it. I can also put you in contact with colleagues and clients in the US if we talk more.
