Fender, Scottsdale, AZ - Lead iOS Mobile Engineer

November 2019 - PRESENT

https://apps.apple.com/us/app/fender-tune-guitar-tuner/id1107017950

Fender Tune - Guitar Tuner App consisting of 2 iOS devs, 2 Android devs, and 2 UI/UX.

●Refactored existing code to support iOS 11+.

●Condensed code to enhance performance and to improve maintenance of codebase.

●Utilized AudioKit to read mic input from device and update UI elements based off readings.

●Made performance enhancements using GCD and NSOperations.

●Collaborated with UI/UX Developers and other team members on all aspects of development: strategy, brainstorming, user research, design, execution, and iteration.

●Accepted input from the device’s microphone

●Configured live updating of UI to inform user of the incoming signal’s volume.

●Configured computing signal (from mic) into a note so that the user knows whether or not the string is in tune for standard tuning of a guitar.

●Customized Autolayout to improve UI based on different user device screen size.

●Utilized Git for code versioning with a GitfFlow branching model and online code repositories.

●Used Grand Central Dispatch to offload intensive tasks to the global thread.

Guitar Center, Westlake Village, CA - Senior iOS Developer

October 2018 - November 2019

https://apps.apple.com/us/app/guitar-center-shop-for-gear/id1173029601
