Hi, I'm Harry Timothy πŸ‘‹

Senior Android Engineer (8+ years). I build secure, fast, reliable Android apps with clean architecture, offline-first flows, and careful performance work.

Creator of SafeBox, a drop-in replacement for EncryptedSharedPreferences with:

  • 184Γ— faster init, up to 50Γ— faster reads, up to 9.25Γ— faster writes
  • ChaCha20-Poly1305 encryption, AES-GCM-wrapped DEK
  • Memory-mapped store with the SharedPreferences API

πŸ“¦ Featured Projects

  • SafeBox
    A high-performance encrypted key-value store for Android.
    Build Release Stars

  • Sanctum (coming soon)
    A privacy-focused journaling app with clean architecture and secure local storage.
