Senior iOS Engineer · Corsica
Apps you hold. Systems you don't see.
I build Finely end to end, and spent years building the platform behind thousands of GoodBarber apps.

All apps
How the systems work
All 9 articlesOne Subscription Flow for Thousands of Apps
How GoodBarber apps sell subscriptions: one shared service shows only what Apple can sell, lets the server confirm every purchase, and unlocks the same access on every screen.
One Layout Engine for the App's Content Lists
How GoodBarber's list templates got one shared layout: the same code sizes and places a list on the home page and on a full screen, measures each item with the view that draws it, and slots native ads between items.
An On-Device Assistant That Never Makes Up a Number
How Finely answers questions about your money on the iPhone: Apple's on-device model only works out what is being asked, and Finely calculates every amount from your own transactions. Without Apple Intelligence, simple rules take the model's place.
Path
About me-
Learning from work in the field
A route-planning app for independent nurses made every interaction concrete: a missed state or unclear step interrupted real work.
-
Working at platform scale
One server-driven system had to serve thousands of customer apps. Changes needed to support configuration, legacy behavior, and gradual migration.
-
Taking responsibility beyond implementation
My work grew to include architecture, StoreKit, WebKit, privacy, lifecycle, SDK migrations, performance investigations, and mentoring.
-
Owning one product end to end
I make the product and engineering decisions across financial rules, interaction, persistence, privacy, monetization, on-device intelligence, and release.
Building an iOS product or platform?
If you are working through a product decision, an architecture problem, or a difficult production issue, I would be glad to discuss it.
