    PHP,HTML,CSS,Java,JavaScript,Perl, Web Developer, MySQL, Linux: 10+yrs

    United States - Last active: 6 days ago - Tests: 6

    I have over 14 years of experience building, fixing and maintaining web applications and their back-ends (large and small). Web programming is my bread and butter- HTML/CSS and whatever drives it on a LAMP or LAMJ stack (PHP, Java/JSP, JavaScript, Perl, etc.). Plus I can administer the technology needed behind the scenes for database setup (MySQL and postgreSQL), maintenance, cron jobs, and systems administration (RedHat/Fedora/Centos or other Linux, etc.) Whether you have just a quick need for someone who knows their stuff, or a larger or ongoing project that might require recurring tasks, I'm here to help. I'm not a Jack of ALL trades, but I also am pretty savvy when it comes to website UI design, SEO and internet marketing, including email and social media.
