    I`m not Indian

    Poland - Last active: 3 days ago - Tests: 6 - Portfolio: 13

    Over the last 4 years, I have developed a wide range of websites using HMTL, DHTML, PHP, JAVA, CSS, AJAX and MySQL including sites for startup companies and small business. I started as a Joomla! developer and moved throughout variety of open source solutions like Wordpress,Magento,Prestashop,Prado,Yii to custom made solutions. I specialize in PHP and JAVA and as a programmer I follow one rule : "Everything is possible". Also I am specialist in data mining, data scraping. I can easilyscrape almost every page and get all the data client needs (given that he knows what he wants). I already have a full time job thus only option for me are small "fix this, do that" tasks. I`m looking for some challenges or brain puzzles that would help break the day-by-day routine for me. Associated with http://ka-design.pl/portfolio
