Speaking
I'm an international speaker and workshop host who loves to talk about technology and communities. If you are interested in having me give a talk or host a workshop, send me an email at juhamattisantala@gmail.com and let's talk!
To your event, I bring a well crafted and polished talk that is educational, entertaining and inspiring. And I'm really good at staying within my provided time slot so you never have to worry about the awkward moment when the time runs out and the speaker isn't finished. I also engage with the community before and during the event, bringing positive energy and happy moments to every event.
If I'm joining your event, you can find my info and pictures from my press kit.

"@Hamatti is absolutely amazing on stage, talking about the importance of teaching in the learning process! #pyconcz"
@webKnjaZ (about I teach, therefore I learn talk )
"Juha is a fantastic speaker to work with. I’ve had the pleasure to coordinate the preparation of his talk for PyConCZ and the communication was perfect. He’s a reliable speaker whose talk was very thoughtful, and I can’t wait to see him on another conference."
