My main experience is with big software products used mostly internal from the companies where I have been working. I have no experience with systems like Joomla or WordPress. The software that I have been working on was written custom for the company needs and relied on MVC framework. In my professional career, I have been working on affiliate software, financial software and CMS software mainly. I have experience with the refactoring of old modules into new and well-integrated libraries. My experience with databases is mainly with MySQL server as I have been working round a year with MS SQL server. I’m good in using foreign keys, transactions and migrations in order to properly handle all data in the database.
