I'm young but experienced web developer. To develop your web applications I'm using HTML and CSS to visual part of it. To give more interaction and effects to the application I'm adding a bit of javascript & AJAX. Everything what is behind the visual part its PHP and MySQL/PostgreSQL. MySQL/PostgreSQL will store your data and thanks to the Stored Procedures and Triggers it will be secure and work fast. My PHP code is always object oriented and optimized by OPcache.
