My greatest strength would be my analytical skills. These help me pick up new programming languages, methodologies and technologies easily.
Though the bulk of my experience has been in communication related software (optical, wireless, TCP/IP), I have had no trouble adapting to web development using Perl, PHP, Ruby (Ruby on Rails), etc.
In addition, I own a Symbian S60 3rd Edition phone (Nokia N95) on which I develop my own applications . These, thus far, are only for personal interest.
