From first idea to production scale.

A few projects that show how I think about product, performance and systems that need to last.

01MEGA · iOSProduction

Making millions of audio files feel immediate.

I designed and shipped MEGA's music player for millions of users. Streaming, system interruptions and huge libraries demanded more than a polished interface — they demanded an architecture built around real constraints.

Challenge A folder containing millions of audios made the player impossible to open.

Incremental batch preloading triggered by playback thresholds.
Validated with Instruments and libraries from thousands to millions of tracks.
Handled in-app calls, phone calls and audio interruptions from apps like Spotify.

Also at MEGA Bringing cross-device backups into iOS.

I turned sparse documentation into a stable integration inside an established architecture, clearly limiting the actions iOS users could perform on backups created elsewhere.
