    Ukraine - Last active: 16 hours ago - Tests: 19

    Seeking opportunities in Perl oriented (Catalyst DBIC preferred) application development, shell and perl scripting, and BSD/Linux administration projects - to build sites and setup servers for your business or pleasure.In my mind, LAMP more often reads as LASP - Linux, Apache, (any|no)SQL, Perl - of course, with Catalyst, Template Toolkit and DBIx::Class/KiokuDB in pair with some RCS (git is preferred, but subversion, mercurial and others also possible). And of course, all can be integrated with AJAX libraries such as jQuery, Prototype, MooTools and other to create Web2.0 apptications.Great knowledge of regular expressions (regexp). Have real experience with MySql, Postgres, Oracle, CouchDB, LDAP, also worked with CPanel, Plesk and Ensim. And of course, have experience with Apache, SMTP (exim, postfix, sendmail), IMAP/POP (Cyrus, UW, Dovecot), firewalls (bsd/ipfw and linux/iptables), Samba and misc ftp and proxy solutions.I can work well as alone and as a team member.

    Senior web developer

    United States - Last active: 10/25/2013 - Tests: 8 - Portfolio: 5

    Over the last 15 years, I have developed a wide range of websites using HMTL, CSS, PHP, and MySQL including sites for startup companies and small corporations. My core competency lies in complete end-end management of a new website development projects, and I am seeking opportunities to build websites from the ground up for you or your business. I am overly competent in database management and have superior knowledge of internet security from experiences from both ends of the spectrum, I have been a hacker in the past and now use this knowledge to better my penetration testing skills.I have many tools that I use to offer clients that guaranteed the most in depth penetration test of their websites. I charge $125.00 for the test, along with a very in-depth compliance report that will explain all vulnerabilities found to you the client. When you hire me for just programming, not only can you rest assured that you will automatically get a secured script and you will not have to worry about sql, xss and csrf vulnerabilities from any part of the scripts that I write. Security is my main focus when writing a script! I have skills in jquery animation, animations with new technology such as adobe edge currently in prototype stage (which will most likely deprecate flash), I have worked on almost every type of website there is from database driven cms, to static html, from real estate websites to javascript driven penny auctions, I have created gaming websites such as knightcrusaders.com, and I also offer server tuning for those who have dedicated servers and find that their websites are just moving to slow, I can optimize queries, tune mysql and php. Again I do have have over 15 years of experience so if there is something I have not listed feel free to ask and I will let you know if I have the ability to do it! I have taken several of the odesk test in order to ensure the client that I do know what I am talking about, I am in top 20% in a few categories which is by far not an easy accomplishment.
