About

Engineer who ships end-to-end

I began my journey as an Android developer and have spent the last four years building production software — from full-scale enterprise field-service apps to a cross-platform product shipped on both Android and iOS. I care about clean architecture, performance, and shipping features that hold up under real-world usage.

I work primarily in Kotlin, with deep experience in Jetpack Compose, MVVM & Clean Architecture, and Kotlin Multiplatform — where I recently shipped an app sharing 95% of its codebase across platforms. Alongside product work, I keep my fundamentals sharp with 900+ algorithmic problems solved on LeetCode.

I've also open-sourced libraries for the community and published an app on the Play Store. I enjoy owning problems end-to-end — collaborating with product, design, and backend to take features from idea to release.
