ABOUT ME
KAWE MAZIDJATARI
C++ programmer & reverse engineer
My name is Kawe Mazidjatari, a 25-year-old engineer from Zwolle, Netherlands, with a strong passion for software engineering and mechatronics.
In the spring of 2020, I started a project called R5Reloaded, an SDK and mod for the game Apex Legends, built on a heavily modified version of the Valve Source game engine. This project has achieved over a million downloads and have garnered more than 150 million views on YouTube and Twitter. It offers a comprehensive set of tools and utilities dedicated to the game’s engine allowing everyone to make mods.
In my portfolio, I would like to present some of my C++ and reverse engineering work involved in the project.
Modified NavMesh toolset for a custom engine using the Recast & Detour navigation library.
