Hello and welcome!

With 10+ mobile games, a multiplayer VR simulator for PC, 5 playable demonstrations and a lot of code snippets (tips) on GitHub, I’m a Gameplay Programmer with experience in developing gameplay mechanics for entertainment and educational game-focused applications. I also have a mobile development background with 10+ applications and 15+ years of software development experience.

Below you can download some of the Featured Projects and play online the Demonstrations.

As an extension of this Portfolio, take a look at my GitHub repository. You’ll see the implementations of the main mechanics that were used in these Demonstrations and some VFX (Shader and Particle) examples.

By the way, if you are a programmer / developer, I really appreciate if these code snippets could help you!
