I was brought on project to perform major feature updates. we were brought on project to first create search enhancements using bloom reach technology. Safeway when we got there had 2 mobile apps loyalty and shop app. Shop App was the more experimental so we tried a lot of new things on it that worked. So ultimately the new goal was to implement features from the loyalty app to the new shop app in a more modular and more efficient way. the end goal was to migrate all features from loyalty to shop and get rid of the loyalty app.

Transitioned iOS apps to Viper Architecture and worked with Viper to create modules that are independent for high degree of reusability and efficient testing.

Migrated the codebase from Swift 3 to Swift 4 and migrated Xcode 9.3 to Xcode 10.1

Successfully resolved a challenge to populate a person profile page with user information from four different APIs seamlessly. This was accomplished by implementing RxSwift library to display information asynchronously.

Responsible for major Contributions to Versions 7.1 - 7.5 of the iOS mobile app.

Third-party tools: SnapKit Adobe Targeting: Adobe Analytics, Quick and Nimble for Behavior Driven tests.

Presentations: Adobe targeting, RxSwift Reactive Programming, Business Chat.

Worked on a team of 3 IOS Developers with 1 lead, 4 Android Developers, 3 QA Engineers.

Worked closely with all teams to make sure we implemented the feature to the best of our abilities.

Viper architecture was used with both programmatic constraints and Storyboards.

Daily standups were part of our Agile Scrum process.

Ensured the code was clean and well-commented.

The team used Jira for task tracking and documentation, and Zeplin for UX comps.

Major contributions to the development of this iOS mobile app included: Search enhancement. Implemented BloomReach search, implementation of native iOS account management, Apple Business chat. Adobe Targeting, and Adobe Analytics.
