Experience

  • Metronome App for iOS
    http://gigbagapps.com/click

    A fully custom UI treatment on this app combines rich, fluid animations and practical features to bring a fresh perspective to the crowded metronome app market.

    I was the designer and developer for this app, creating everything from the real-time audio processing pipeline to the custom rotation animations and extensive UITableView customizations. I also created an innovative circular menu system to achieve a unique, minimal look.

  • Lead Generation App for Roofers and other Home Contractors | iOS
    http://leadscoutapp.com

    A Swift-based app for roofers, landscapers, etc., and their teams to collaborate on generating new leads and advertise for their business.

    I was the iOS developer and worked directly with the back-end and web teams to bring the full host of features available from the service into the mobile app. I helped to design the system for data synchronization between team members. I took 100% ownership over the new features and bug fixes for the mobile app, including integrations with Google Maps and other third-party services, alongside a custom Rails back end.

  • theDrumDictionary | iOS App for Drummers
    http://gigbagapps.com/thedrumdictionary

    This project involved the complete rewrite of an outdated iPhone app in Swift UI. It brings the app into the modern era with full native support for all iOS device screen sizes, as well as macOS support. I revamped the audio system to allow for better controls.
