Lasse has spoken at dozens of international conferences since 2005, including a couple of keynotes in agile conferences, speaking to some 2000 programmers in a movie theatre, addressing staff of the European Commission (they actually organise an IT conference of their own), and a bunch of smaller gatherings.

Lasse has occasionally done workshops, too, and taught more than a thousand people in classroom settings across three continents during the past decade.

He happens to be a Certified Scrum Trainer as well (one of the few who write code for a living) and wrote a couple of books about unit testing and TDD, which consequently led him to talk about those topics to a lot of people.
