I am Kostas Bariotis, a software engineer from Thessaloniki, Greece. I am passionate about clean code and an advocate of that success is in the detail. I am interested in designing software architectures, APIs and databases to serve the rest of an application. My career path started with building e-commerce projects using various known platforms like Magento and Wordpress.
