VOXA — Solo-Built Full Stack Music & Culture App

This is VOXA.

A Cultural Music and Language Ecosystem, soon to be released on mobile app stores.

The original purpose of VOXA was to remove the barriers of language in music without disrespecting the original art and culture. VOXA has since grown from what was the singular original feature, VOXA - Lyrics and Language (the screenshot on the far right), into an ecosystem with multiple different features and a music player for our home-grown record label that supports an interactive stem player.

VOXA today includes: an AI-powered lyrics translation engine that captures cultural and slang context, not just literal word-for-word meaning; an interactive stem player for isolating and remixing individual tracks in real time; a gamification system with quests, XP, levels, and global rankings; a subscription system built on RevenueCat across iOS and Android; and VOXA Records, an in-app record label releasing original music directly through the platform. Every feature, from concept to shipped code, was designed and built solo.

One of the hardest technical challenges was building the interactive audio stem player — allowing users to isolate and blend vocal, drum, bass, and melody tracks in real time from a single song. This required custom code beyond FlutterFlow's standard components, careful audio buffering to prevent playback lag, and Firebase Storage architecture optimized for fast streaming of multiple simultaneous audio files. I also had to solve cross-platform layout issues to ensure the UI rendered correctly across different device sizes, including extensive testing and iteration through Apple's App Review process.

A second major challenge was the translation engine itself. Rather than a simple API call, I built a system that routes licensed song data through our partners for lyric retrieval, then layers cultural context and slang interpretation on top — meaning the translation reflects how language is actually used, not a literal dictionary conversion. This required careful handling of latency across multiple chained API requests while keeping the user experience feeling instant.

Beyond development, I designed VOXA's complete visual identity — the UI system, color palette, custom illustrations, and brand voice — ensuring the product feels cohesive across every screen, from the core app to the record label's music player.

VOXA is currently completing App Store and Google Play review. Alongside the app, I've independently built and delivered client work using the same skill set — including a full website and booking system for a local business in Mexico — demonstrating the same product thinking and technical execution applied to real client needs.
