  • Implement and enforce rigorous security measures, including biometric authentication, secure token storage via Android Keystore, and robust MFA flows
  • Translate design specifications into pixel-perfect Material Design interfaces, ensuring intuitive user flows for complex financial actions.
  • Write comprehensive unit and integration tests, participate in rigorous code reviews, and monitor/resolve crashes promptly
  • Profile and optimize the application's speed, stability, and resource usage across a variety of devices

  • Demonstrated experience in implementing mobile security best practices for financial or sensitive data applications (Keystore, Certificate Pinning, Obfuscation);
  • Proven ability to write effective Unit Tests (JUnit, Mockito/MockK) and strong debugging skills;
