PROFESSIONAL EXPERIENCE:

Confidential, Ann Arbor, MI

Senior iOS Developer

Responsibilities:

• Diagnosed bug reports found with Crashlytics and resolved them examining the codebase and using the Xcode debugger

• Converted all Swift 2.3 code to Swift 3.0 and maintained dual code base with Objective-C for legacy support
• Used Git for version control and reviewed pull requests to ensure that all submitted code conformed to best practices and was sufficiently tested
• Leveraged the Kiwi framework for testing
• Developed and expanded internal framework/SDK to encapsulate functionality and share among different platforms, including iOS (iPhone, iPad), watchOS, and Ford Sync
• Performed modifications of build jobs to fully utilize Cocoapods for Mockingjay integration
• Worked in an Agile environment and used JIRA for ticket tracking and sprint management
• Delivered code using Jenkins for Continuous Integration
• Used AutoLayout throughout Interface Builder with Xib and Nib files to ensure that the application looked great on all device sizes
