Roozbeh Zarei

I'm a mobile app developer with a passion for crafting apps that knock people's socks off!

Armed with a degree in Computer Software Engineering and Google's official Android development training, I've sharpened my skills into those of a certified code ninja! I've also launched a few open-source projects that have been downloaded by thousands, showcasing my ability to turn ideas into digital reality.

When not busy squashing bugs, you'll find me exploring the depths of the internet, staying ahead of the latest trends, and fueling my curiosity for all things tech.

What I Do

Mobile app development

Whether it’s a native Android app powered by Kotlin or a multiplatform one with Flutter, I’ll build an application that’s fast, intuitive, and ready to shine on any device.

Backend as a service (BaaS)

Turbocharge your app's reach and engagement with Firebase. From user authentication to targeted push notifications and cloud storage, I'll equip your app with the tools it needs to thrive.
