Summary
👤
Senior🎓
Top SchoolJacek Kuźniarski is a Senior Android Engineer based in Warsaw with 14 years of hands-on experience building and maintaining mobile platforms for startups and large vendors. He has led platform efforts and sustained complex Android projects at Neofonie and Huawei, and now drives Android development at Fresha. Comfortable across the stack, his background includes AOSP work, kernel/OS-level customization, large-scale syncing and server-defined UIs, and pragmatic solutions for sensitive user data. Known for mentoring peers and turning research into production-grade features, he pairs deep technical curiosity with a taste for practical engineering craft. Outside work he’s into tactile hobbies—yoyoing, mechanical keyboards, and social tinkering—which mirror his attention to low-level detail and ergonomics in mobile UX.
