Hi, I'm Rafanomezantsoa Sariakiniaina (aka s4r14k). I am a passionate software engineer, game developer, and educator. Guided by the philosophy that the "Virtual world can change the real world", I focus on crafting highly polished interactive experiences and clean architectural systems.

I run the YouTube channel EIS Dev, dedicated to game development and programming tutorials. I also authored the popular Udemy course "Make a 2D platformer in Unreal Engine 5 C++", teaching over 250+ students how to build professional player-enemy interactions from scratch.

In addition, I build and publish Unreal Engine templates and plug-ins on the FAB Store, including the Dialogue Widget, Minimap System, and a 2D Platformer template. My web stack is focused on high-performance frameworks like React & Next.js.
