Problem
Musicians need responsive mobile tools for recording, mixing, looping, and live audio processing without desktop software getting in the way.
My Contribution
Designed and developed native Android music apps covering app logic, UI, audio engine work, Firebase services, and automated testing.
Technical Work
check
Built Kotlin Android interfaces for recording, mixing, sequencing, looping, and live controls.
check
Worked on C++ audio processing paths for low-latency effects and instrument workflows.
check
Connected Firebase Realtime Database, Cloud Functions, Analytics, and release-support tooling.
check
Added automated coverage with Espresso, UIAutomator, JUnit, and Mockito where it was useful for product stability.
Outcome
The work produced a family of practical Android music apps that can be shipped, tested, and iterated independently.
Highlights
Full product ownership from app architecture through release support.
Mix, FxRack, Looper, MIDI, instrument, and studio workflows share a related technical foundation.
Audio work connects native mobile UI with performance-sensitive C++ implementation.
