Radu Mazilu - eMAG IT Research
Course - Which data storage to choose - from flat files, through SQL, NoSQL to massive distributed systems
I appreciated Folio's wide breadth of knowledge. Not only was he familiar with the course content, but he also knew of constructs in languages we were familiar with to make examples more meaningful to us. During intervals he shared his knowledge of technologies and solutions outside the training scope to provide insights into other solutions we could use in future (and future training).
