OromarGo TV

Apple TV and Android TV app for Oromar TV, built from the same Expo codebase as the OromarGo phone app: a single build flag switches the native target, swaps each screen for its TV variant and stubs the modules a television doesn't have. The UI is designed for a remote: a collapsible side rail, a hero carousel, and rows for what's on now, continue watching, programs and latest clips, all driven by spatial focus navigation. Live channels come with a TV guide and a channel rail; episodes play full screen with 15-second skips. Nobody types a password with a remote: the TV shows a QR code, the phone that is already signed in approves it, and the session lands on the TV through a one-time Clerk sign-in token minted by a Supabase Edge Function.

SECOND OPINION

13+ years · product, architecture, team · ES / EN

When you need judgment,
not just code.

Not every engagement needs someone to take the whole product. Sometimes you already have a team and need someone who has shipped this before to look at it. A decision nobody can settle, a stack under evaluation, a roadmap that feels wrong, an estimate you do not trust. A decade of shipping across web, mobile and AI left me something more useful than a stack: judgment about what is worth building.
