Who I Am

About Me

I'm a passionate Android Developer based in Chandigarh with 2.8+ years of professional experience shipping production Android apps. Core stack: Kotlin & Java, with deep expertise in MVVM, Clean Architecture, and Jetpack components.

At i-Next Web Technology, I've shipped HappyTask, BaOui, and Hebrew Theme App to the Play Store — owning the full cycle from architecture decisions to Play Console release tracks. I collaborate closely with iOS & backend teams and handle direct client communication.

CS graduate with a CGPA of 8.12, strong foundations in DSA, OOP, and systems. I care about clean code, great UX, and building things users actually love.
