Still a hobby developer, I'm now focusing on building 3D games and VR / AR / XR experiences & tools, using C# and Unity almost exclusively.
During these years I stepped away from web development and spent a lot of my personnal time learning Machine Learning with Python and Jupyter notebooks. It was a great experience from a learning point of view, even though I'm afraid I didn't build/release anything special out of it !
Now working full time at Adobe, I went back to just being a hobby developer. During these years I mostly coded for fun in javascript - both front end and nodejs - often in the context of developing plug-ins and extensions for various Adobe Creative Cloud apps, and other developer tools in the creative coding ecosystem.
I started my career with Flash and ActionScript, as a consultant, teacher and publisher. For all the bad press it got later, Flash started as an incredible creative tool, open to a diverse range of skills and backgrounds, which is probably why the community was so amazing.
