    Before programing my greatest passion was mathematics, and it was problem-solving that led me to programming in the first place. With every website and database being unique it is always easy to find enjoyment in working on a new project and with new clients. I understand the importance of engaging with clients and making predominantly positive customer satisfaction. You can expect honesty, trust, integrity, and hard-work ethic from my work. A passionate and creative approach to any project, with full dedication and motivation to it will result in fast replies and deadline meeting at all times. I am familiar and comfortable working with both front end JavaScript, CSS3, HTML5, jQuery and back end MySQL and PHP. All in the purpose of making aesthetical and functional website, either for your starting business or already well-developed company.
