Hi, I'm Raju
Android developer with 8+ years of experience building production-grade mobile applications.

I specialize in native Android development (Kotlin/Java), AOSP firmware customization, and Kotlin Multiplatform. Over the years I've shipped 20+ apps with over 500K cumulative downloads across finance, logistics, and consumer domains.

Beyond standard app development, I have deep experience with system-level Android — custom ROMs, kiosk solutions, secure banking applications, and anti-reverse engineering techniques. I prefer clean architecture, modular code, and building systems that scale without unnecessary complexity.

  • 20+ production Android apps shipped
  • 500K+ total downloads
  • AOSP firmware from Android 11 to 15
  • Custom ROM & kiosk solutions
  • Secure banking & fintech apps
  • Anti-reverse engineering expertise
Based in Ahmedabad, India — open to remote collaboration worldwide.
