I am a frequent speaker at conferences (Devoxx, Spring One, etc) and user groups around the world.
My main topics are on Java, JHipster, Spring, Azure and AI: most of my talks are live-coding sessions or workshops, where I show how to build applications using the Open Source projects I contribute to.
Here is a list of YouTube videos that I try to update frequently.
If you would like me to talk at one of your events, please contact me.
Most of my work is done through workshops, so if you attended one and are looking for the code, it's very probably available on my my GitHub page.
Most of my talks are live-coding sessions, but when I do presentations they are uploaded on my Slideshare account.
