· The long version

Marco builds the mobile work — React Native when a project needs both platforms quickly, native Swift or Kotlin when it needs the last ten percent of polish.

He profiles cold-start times obsessively, on real low-end hardware rather than a simulator, and he has been known to reject a perfectly good animation because it cost forty milliseconds on a four-year-old Android.

The App Store reviews on the last app he shipped mention the interface more often than the features. He considers that the scoreboard.

Nobody reads your changelog. They feel your launch time.
