Gio Scalzo is an Engineering Lead at NewDay who has been building mobile products since 2009 across iOS, Android, React Native and Unity.
He is not attached to any single language or platform; he cares most about creating useful digital products, and sees mobile as the most direct and accessible way to reach people.

At NewDay he leads AI-accelerated development practices, helping mobile teams bring coding agents and AI tooling into their everyday workflow in a practical, low-friction way.
He has written several books on Swift and SwiftUI, including *Swift by Example*, *Swift 2 by Example* and *SwiftUI Cookbook*.
He is the creator of AI-powered consumer apps such as "Pocket Sommelier "and "Flora AI", and award-winning children’s games with Lola Slug, including "Noah’s Ark Animalibrium", which has been recognised by Apple and international juries, and the creative play app "Coloring Garden".

Gio regularly speaks at meetups like NSLondon (Google London) and Londroid about real-world AI-assisted mobile development, sharing hands-on lessons from teams shipping production apps with AI in the loop.
