PROFESSIONAL EXPERIENCE

iOS Architect

Confidential, Oakland, CA

• Led team that maintained and added features to the main view of the app which contains recently played stations and suggested stations as well as browsing
• Implemented extension on UIImageView that utilized the networking layer to asynchronously fetch album art to display in custom UITableViewCells
• Built and modified fetch functions to obtain updated information from Pandora proprietary RESTful APIs on the users preference, recently played stations, and suggested stations
• Built and maintainedPOST method to send user selections, favorites, played stations, etc. to server to enable syncing between devices and to enable data analyzation to enhance further the ability to make relevant suggestions to the user
• RESTful API fed data by devices connected to account to process with proprietary algorithms to build a taste profile and help users discover new music
• Custom implementation of UITableView with customized UIButtons and multiple customized UITableViewCells
• UISegmentedControl implemented to provide easy sort order for main view by most recent, or alphabetically
• Protocols and delegation employed to communicate and pass information between UIViewControllers
• Custom UICollectionViews, UICollectionViewCells to provide visually appealing browsing experience of podcasts, genres, artists, decades, new music, moods and activities, top artists and stations, and rising artists
• UIViewController subclassed and customized as a detail view to hold UITableViews and UICollectionViews to provide the ability to expand sections when browsing, as well as UINavigationController to provide navigation back to the browsing view
• Guided, mentored, and led team consisting of senior and junior developers and interns
• Team leadership responsibilities consisted of one-on-ones, code reviews, best practices, as well as taking lead in Scrum meetings

Lead iOS Developer

Confidential, San Francisco, CA

• Senior lead developer for search functionality in app which includes the ability to filter results based on price range, keywords, number of bedrooms and bathrooms, property type, etc.
• Utilized delegation and protocols to facilitate communication between the filter UIViewController and the search ViewController to handle the filtering mechanism for searches
• Alamofire employed to make network calls to proprietary API for synchronization and data retrieval
• Employed Google Maps SDK as maps provider using CocoaPods as dependency manager, in conjunction with Core Location and reverse geocoding to get user location
• Utilized a custom implementation of GMSMarker to place clickable pins onto the map to display the location of available properties
• Connected with 3rd party services to provide information on neighborhoods, crime rates, etc. and create layers for the map to display this data
• Crowdsourced neighborhood insights from local users to build up propriety database and add business value
• Lead team in the the decision making process for things such as what architecture to use for the app
• Took lead ensuring meetings stayed on track and were productive
• Responsible for communications with non-technical stakeholders such as development time, complexity of new feature requests, etc.
