Hi, I’m Mohsen Abd Elkareem, a Senior Android Engineer with 10+ years of experience building scalable, high-performance Android applications using Kotlin and Jetpack Compose. I specialize in designing clean architectures, mentoring Android teams, and delivering robust, production-ready mobile software. I’ve led initiatives that reduced crashes by 30% and ANRs by over 20%, improved performance across large codebases, and implemented offline-first architectures with Room and WorkManager. I’m open to remote contract opportunities with overlap with US time zones.
