Podczas szkolenia zostały bardzo szczegółowe - jak na dwa dni szkolenia - omówione wszystkie moduły, a na tym mi najbardziej zależało.

Course - SQL Advanced
It was the best remote training I have ever attended. Even though the trainer did not force contact with the participants or become familiar in order to gain attention, he constantly gained my attention. The substantive level is very high. :)

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).
