Schneider Electric

https://apps.apple.com/us/app/myschneider/id714825126
Schneider Electric is one of the largest companies in the electrical equipment industry. The company already had a mobile app in Objective-C, and our mission was to rewrite the app in Swift using the latest technologies and best practices. I set up the VIPER architectural pattern, led technical discussions, and mentored other iOS developers.

Mobile App for the Beauty Community

An iOS application for users interested in following makeup artists and finding new makeup products. In addition, content creators could share their makeup looks and tag the products they used so that other users knew exactly how the look was achieved. I led three developers to deliver this app.

Bewifi is an iOS app that allows users to find and connect to places offering free wifi hotspots.

A beautifully designed Swift-based app for startup founders interested in receiving a collection of curated and practical lessons from the best books, blogs, and talks.
