Whatever I need to be good at when I start working on a project. I usually have an idea first, then if I have any gaps in my knowledge, I get some materials from the net before jumping in the creation process. I am a very quick learner and I gained most of my knowledge from tutorials autodidactically rather than from the university. I am more of a scientist then an artist.
The latest technologies. I want to make a huge impact on the future. Creating tools to help science fictions become reality, especially now, that HoloLens is on its way.
I've worked with graphics, 3D modeling and programming for mainly scientific purposes (retargeting), I've also used Unity3D for game development.
