iOS engineering portfolio

Stephane Lanfranchi, Senior iOS Engineer

I build iOS systems that remain reliable under product, platform, and legacy constraints. My work spans reusable UIKit architecture, StoreKit, WebKit runtimes, performance, and privacy across seven years of production applications.

  • UIKit architecture
  • StoreKit & subscriptions
  • WebKit runtimes
  • Performance
  • Privacy systems

Selected work

Engineering case studies

Production systems examined through their constraints, architecture, failure modes, and long-term maintenance costs.

Current personal project

Finely

A native iOS finance app for healthier money management through income, expenses, recurring subscriptions, privacy controls, and Pro features. I use it to explore modern product-level iOS work through SwiftData, StoreKit 2, recurrence rules, notifications, and system integrations.
