About Federico

Hey there! 👋 I mainly work in Swift and SwiftUI and I enjoy making apps that not only work like a charm but also look stunning. I can design the architecture and develop the entire app or collaborate in specific parts (maybe building just the front-end, building a feature, etc).

✔︎ Fast-prototyping in SwiftUI
✔︎ Structured concurrency
✔︎ Firebase expert
✔︎ iOS widgets and Live Activities
✔︎ Apple frameworks like Mapkit, Tipkit, Core Data, Swift Data, Core Image, AVFoundation, among others.

Federico is so good that I waited for three projects before reviewing him - he is a rare find, and I wanted him all to myself! But as this is hardly fair to him here comes my honest review: We encountered a major roadblock while trying to integrate a WebRTC connection into our iOS app. After spending a month on this with other developers, we were stuck. Although Federico initially mentioned that WebRTC wasn’t his area of expertise, he generously offered to take a look at it—without charging for the exploratory work. In just one week, he not only recreated all our previous progress but also resolved the issue swiftly, charging us only for the actual solution. Federico is incredibly intelligent, resourceful, and adaptable. He’s always willing to go the extra mile—even clearing his Friday evening to help us with an urgent issue the night before a key presentation. After solving the WebRTC problem, he also developed a cloud-based backend for our iOS app, seamlessly integrating various API services. The solution has worked flawlessly since its deployment. Then he adapted the app to VisionOS and even though this proved more time consuming then initially expected he completed the whole task perfectly according to the initial offer. Federico is professional, highly responsive, and a pleasure to work with. His dedication and ability to tackle complex problems make him a standout developer, and I wholeheartedly recommend him.
