    Since 2010, when I took up web developing professionally, I have developed a wide range of sites using up-to-date technologies such as PHP, MySQL or JavaScript. My work includes full site development from features analysis and design to coding. I can dig into an existing project with ease and tweak it to meet the client's requirements. I am a quick learner and have thorough knowledge of PHP (both structural and object-oriented programming), SQL and JavaScript, which allows me to get a hold of new libraries and techniques really fast. I am constantly developing my skills by studying new methodologies so I can be a solid contributor to the projects I am working on. In recognition of my skills I was granted the title of Magento Certified Developer in May 2013.
