About

Short version.

I turn ideas into real products.

I'm a CSE student and Android developer. I learn by building and shipping actual projects rather than only following tutorials.

I work mainly with Kotlin and Jetpack Compose, and I'm interested in product engineering, mobile development and building startups.
