@wasifnadeem1

I build secure, high-performance Android chat apps in Kotlin for thousands of active users.

At NiteSun Technologies, I lead development of a secure native Android chat application used by 5,000+ active users. I’ve delivered production releases with real-time messaging, offline synchronization, and end-to-end encryption backed by Android Keystore.

I build Android products in Kotlin and Java using Jetpack Compose, MVVM, Clean Architecture, Coroutines, Flow, Room, and REST and GraphQL APIs. I also improve reliability, performance, test coverage, and security while mentoring developers and reviewing code.
