    The PHP professional you can rely on

    Canada - Last active: 04/27/2013 - Tests: 13 - Portfolio: 1

    Since 2002 I've developed dozens of applications in real estate, communication, billing, productivity, affiliate marketing and many other areas. My favorite server side technology since then is PHP, which is a very powerful tool in professional hands. I use CodeIgniter, CakePHP and love Wordpress. Dealing with LAMP stack, I've mastered Linux user and administrator skills. Finding bottlenecks and server optimization for huge load projects using VPS or cloud platforms like Rackspace or Amazon. Although I am not a graphic designer, I know my way around handling graphics, HTML and CSS. My principles are create good quality code, think ahead, be creative, foresee and prevent failures. I am seeking for the challenges to build complex web applications from the ground up. Find more on my blog http://a32.me

    Senior telecoms developer/CTO

    United States - Last active: 6 months ago - Tests: 2

    I've been developing software commercially for more than a quarter of a century, both as an employee of large organisations (IBM) and, to a greater extent, as my own boss. I've built and sold two businesses along the way, learning a great deal from having done so. My focus has been on telecoms. I developed TDM IVR systems based around Aculab and Dialogic cards in the late 1990s, and have, more recently, been involved in developing IP solutions using Asterisk, Kamailio and FreeSWITCH. These have included an IP Centrex platform (Asterisk and SER), a carrier-grade softswitch (FreeSWITCH) and various IVR solutions (Kamailio and FreeSWITCH). I'm fluent in a number of languages, including C, PHP, Perl, C# and Javascript, am happy to develop on Windows or Linux and have been using Agile development methods - in particular, release early and often - since before the term Agile was coined. I'm experienced with managing small teams of developers, and understand the importance of delivering the agreed product on time and within budget.
