Band Guide multi-device stage performance interface

Overview

Band Guide is a multi-device live performance platform for singers and musicians, focused on setlists, lyrics, chords and real-time stage coordination.

Problem

Live performance workflows can break down when singers and musicians do not share synchronized setlist state, song order and stage context.

Implemented solution

The system provides role-aware Android workflows, Firebase synchronization, setlist management and explicit live publishing for coordinated performance use.

My role

Product analysis and requirements definition.
Architecture planning and AI-agent tasking.
Implementation supervision across frontend, backend, database and platform-specific surfaces.
Debugging, test planning, acceptance review, deployment preparation and iterative improvement.

AI-native development workflow

  1. 01

    Requirements are converted into structured implementation tasks.

  2. 02

    Codex and AI tools are used for code generation, investigation and refactoring.

  3. 03

    Major tasks follow a READ → BACKUP → PATCH → VERIFY → TEST discipline.

  4. 04

    Human review controls architecture, acceptance, security decisions and release readiness.

  5. 05

    AI is used as an engineering accelerator, not as a substitute for validation.

Technical overview

Built with Android, Java, Firebase Authentication, Firebase Realtime Database, SharedPreferences, Android Keystore, Gradle, JUnit and ADB.

Key engineering challenges

Coordinating singer takeover, musician follow-live behavior and device-specific presentation requires careful state separation.

Testing and verification

107 tests
0 failures
0 errors
0 skipped
Gradle build PASS
Repeated real-device multi-device tests

Product positioning

The implementation includes the capabilities presented in this case study and is designed for continued product evolution.
