It is Vincenzo Stira boosted and augmented by Artificial Intelligence focused on Apple Platform.
A selection of shipped work across consumer apps and platform tooling — from 1M-user products to the architecture and pipelines beneath them.
MONOIDX is the digital engineering identity of Vincenzo Stira, an Apple platform engineer building software for iOS, iPadOS, watchOS, macOS and visionOS.
The practice is built on a single principle: clarity through restraint. Every system is designed for longevity, reduced complexity and resilience—software that stays invisible and simply works.
Today that work is boosted and augmented by Artificial Intelligence. AI accelerates research, architecture and implementation, while the engineering judgment stays human. The result is a workflow that ships faster without trading away craft.
In mathematics, a monoid is the minimal structure you need to compose things reliably. Two rules. No waste. Maximum reuse. That's how I approach engineering.
I'm a Senior iOS Engineer with 13 years of experience shipping production apps on the Apple platform. I work at the intersection of mobile craftsmanship and AI-augmented development.
I built MONOIDX as digital identity for this purpose. MONOIDX is me to the nth power.
iMamma is one of Italy’s leading maternity and parenting apps, with over 1M users and a 4.7-star App Store rating. The product is built on a Kotlin Multiplatform architecture: domain logic, networking, persistence, sync, and MVI state machines live in shared Kotlin (compiled to an XCFramework and owned by the Android team), while the iOS app is a thin native layer on top.
My role was on the iOS side. I built the SwiftUI presentation layer and the bridge to the shared MVI components, observing Kotlin-exposed state Flows through SwiftUI and dispatching user actions back as Intents.
I worked on a generic UIHostingController wrapper and a routing layer mapping shared routes to SwiftUI screens, and delivered features across the app’s trackers (sleep, feeding, nutrition) and Tools section. I made the project fully reproducible via XcodeGen and a Makefile, and integrated the AppsFlyer SDK for attribution and deep linking, including ATT consent handling.



Native iOS application for Eolo, an Italian fixed-wireless broadband (FWA) provider, serving as the customer-facing companion app for account management, connectivity diagnostics, and payments. The project originated from a previous development effort at another consulting firm. The client wanted to retain the existing codebase and integrate and add new features to it.

Sometimes I use my proof-of-concept projects as a training ground and lab to experiment with and implement the latest Apple technologies. This POC aims to explore the possibility of creating an unofficial fan app for the Palermo F.C. soccer team that is entirely native and can take full advantage of the capabilities offered by iPhone hardware.
The idea, therefore, is to create a native app for high-end iPhones that makes extensive use of graphic effects and animations in both SwiftUI and Metal. Fans will be able to follow their team through a premium experience that includes gamification with geotagged tags, AR, and extensive use of artificial intelligence—which, through RAG, summarizes all the news on the web about the team and the transfer market.
One of the sections will be dedicated to community engagement. A proof of concept (POC) for the community section is available below among the links.
A food guide based on the community’s experience, that focuses on dishes and not on restaurants. Available on iOS and Android, SnapFood does not just tell you where to eat, but where you can eat the best dish you’re looking for.

Some experiments conducted way back in 2015, when Apple did not yet have its own augmented reality library but there were some third-party libraries that made it possible to create the first AR prototypes.
In the first video, I demonstrated, during my time at Informamuse—a proof of concept (POC) showing how, in 2015, it was possible to create AR products using the VuforiaSDK library. Specifically, the POC showcased a potential feature for a museum app in which visitors, upon approaching an exhibited archaeological artifact, could see what that artifact looked like when intact and viewable from every angle thanks to Augmented Reality.
In the second video, a similar POC but performed on 3D models.
This demonstrates my general inclination to continually experiment with new technologies.
Some experiments conducted way back in 2016 when Apple did not yet have its own AI frameworks but there were some third-party libraries that made it possible to create the first AI prototypes. It wasn’t yet the era of LLMs and AI was limited to machine learning and OCR scanning.
The first video is about IBM Watson AI. The second video is about Vuforia SDK and IBM Watson AI. The third video is about PBR with a fresh new Apple Framework presented at wwdc 2014: The Metal Framework
