About the conference
DevTeach stands for Developers Teaching Therefore, It is a conference done by developers for developers. These events have all the elements of an international conference with speakers coming from all over the globe but keeping the values we all treasure from local community events. We pride ourselves in offering the biggest diversity of subjects covered in our various sessions. All our sessions provide presentation material to the attendee and whenever possible, hans-on training. DevTeach is not so much a conference as it is a “developer festival.
