We have covered a lot of different topics in a short time

Aurelien Petit - Prostep

Course - Spring 5

Machine Translated

A vast amount of practical knowledge was also conveyed in a practical form. I liked that the trainer is a practitioner, so discussing individual topics was enriched with real-life examples and best practices. It's clear that the trainer is passionate about technology and enjoys (and can) share their knowledge further. I wish for more such training sessions for myself and other trainees :)
