Bartosz Górski is a Magento developer with four Magento certifications (Developer, Developer Plus, Front End Developer, and Solution Specialist). He's been working in the web development/programming field for over 7 years and has over 3 years of experience in developing solely on the Magento eCommerce platform.

He is a big fan of doing things the right way, so he always aims to write as clean and efficient code as possible. He's always happy to give and receive feedback on how a given piece of code can be improved (this is why he does technical reviews of Magento books for Packt Publishing from time to time).

When he's not at work, he's probably playing pool somewhere or sitting in his office, browsing camera lenses on eBay and complaining how little time he actually has to take some photos himself.

Amr Shahin is a professional software engineer who caters to a wide array of companies. He works for a well-known company named JRD group. Amr resides in Dubai, UAE, where he spends most of his time when he's not at work. He uses his spare time playing football, listening to music, and reading books to widen his knowledge.
