Currently not looking for job. I'm a professional PHP Developer. Over the last years, I have developed a wide range of websites and web services for small businesses, large corporations and individuals. Most of my projects have been CRM/ERP/SFA systems. I have developed projects in the fields of offline retail, sport tracking apps, e-book sales, auto repair, media marketing and much more. I do not just code, I delve into the client's problems and solve them. Many projects done by me involved working tightly using 3rd party REST and SOAP APIs like: Amazon MWS, Ebay API and other public APIs like Facebook API and Google API. In addition I love to perform tasks of scraping and user actions automation. Given the choice when starting a new web app, I prefer to use Laravel with MySQL, Bootsrap and Vue.js. Technologies OOP PHP (5/7), MVC Frameworks (Laravel, Yii, Yii2), SQL Databases (MySQL, MariaDB, Postgres), Bootstrap, HTML/XHML/XML, Core JavaScript / jQuery, Git, Selenium WebDriver, UNIX / Linux / OS X operating environments.
