Programming (in Perl and C)

MARKOV Solutions is the free-lance company of Mark Overmeer.

My first contact with computers dates back to 1980 (before the first PC was born), when I was member of a "Young Scientists". Some bright guys had built their own computer with an astounding 2 kB of memory.

I have programmed in about 30 programming languages since, amongst them various machine code and scripting languages. The languages Perl and C have my preference.

In Perl, I developed and maintain a large number of modules, as can be seen on my personal Perl pages. Often, I give talks on International Perl Conferences. Programming in C was my full time job during more than ten years.

If you want to benefit most from my abilities, hire me to

• program Perl or C, (or any other Unix based language),
• code auditing,
• rewrites of existing, unmaintainable code (software pathology), or
• configuration of a software development environment.

I solely develop on a Linux platform, although my products are usually platform independent. My preferences are with complex, technical problems, and less with database applications or websites.
