Hi, I'm Hamidreza Sahraei—a Senior Android Engineer based in Vienna, Austria. Over the past several years, I've developed high-quality Android apps used by more than 55 million users worldwide, focusing heavily on scalability, performance optimization, and smooth user experiences.

I love creating solutions that solve real-world problems and helping developers master modern technologies. Now, I'm here on Udemy to share everything I've learned with you—from clean architecture, advanced testing, and high-performance Android development to cutting-edge tools like Kotlin and Compose Multiplatform.

When I’m not coding, teaching, or exploring new technologies, you'll probably find me performing card magic tricks, spending quality time with my cat, playing video games, or serving aces on the tennis court.

Let's have some fun while we build the future of mobile development together—see you inside!
