About Me

I've been working with Android development for over seven years, focusing on Kotlin and Java as the main programming languages. I'm a Flutter enthusiast with an application published on Play Store. I have worked on projects across social media, food delivery, real estate, fintech, e-commerce, and transportation. It's important for me to share knowledge at every opportunity through mentoring and support for other developers.
