About Me

I'm Jean-Sebastien Royer, and I'm/was a Freelancer/Indie Developer/Software Engineer.
Above, I’ve shared some of my projects. Below, I’ve included some random stuff about me and information to get in touch with me.
Have a nice day,


I'm a passionate developer who likes working on all areas: 3d/graphics, low level, core, gaming, audio/video, networking, etc. Skills: Optimization, technical, problem solving, pushing the limit, autodidact, creativity.


I began coding at 13 years old on my 386DX 40mhz in Basic, followed by Turbo Pascal, Assembly, C, C++, Java, and more. One thing that awoke my passion for coding was the demoscenes and especially this one.


I always work on 1-3 projects at a time. I think it's a good way to improve yourself, learn the latest tech/trend, and realize your dreams. And one of the most important things for me is materializing my projects.


I'm an huge fan of retro gaming ( Contra, Super-C, Castlevania, Mega Man, ...) and Indie games like Super Meat Boy, Minecraft, Braid, Limbo, Papers, Please, ...


I'm Canadian and living in San Francisco. I’ve had the opportunity to travel/work in Italy, Japan, Bulgaria, Morocco, Spain, and the USA.

Great minds discuss ideas;
average minds discuss events;
small minds discuss people.
