Android Mentoring

  • Kotlin and Jetpack Compose
  • Testing and release readiness

AI Integration

Use AI to solve real problems instead of shaping your work around a tool. I'll help you choose useful applications and stay in control of the result.

  • Start with the problem, not the tool
  • AI in existing workflows
  • Verify outputs and keep decisions in your hands
