WORK EXPERIENCE:

Confidential, St Louis, MO

Senior iOS Developer

Responsibilities:

• Main emphasis on this particular project was user interface; I worked heavily with core graphics, core animation, UIViewAnimateWithDuration, and UIDynamics to spruce up and make the app more enjoyable to use
• Application is compatible with devices running iOS8+
• App was originally XIB based but was migrated to a multiple storyboard setup for smarter easier setup
• Lots of work with size classes to handle all possible screen sizes; priorities where managed to ensure no conflicts arose between constraints
• UIImagePickerController within AVFoundation was used to capture/scan credit cards, or barcodes/QRcodes; POC’ed Scandit and RedLaser
• Worked heavily on the shopping cart portion of the application; Coredata was used to ensure the shopping cart information was never lost regardless of user logging out, loss of internet connectivity, or any other miscellaneous occurrence
• Knowledgeable interacting with CoreData in multithreaded environments; the practice of confinement was followed per Confidential ’s suggestion, so multiple managed object contexts used. Each background thread would have a child context from a parent context residing on the main thread, saving of a context would fall back to a parent
• POCs and development involving primarily the shopping cart functionality of the application were completed in Swift 2.3. With the intention to evaluate and determine ease of code migration, and development for future features of the application.
• All multithreaded executions were managed by Grand Central Dispatch calls
• Distributed team required lots of communication via email, Lync, skype, and such; accurate and precise communication was primordial due to time zone differences as well
• JIRA was used for tracking and assigning of
• Lightly worked on Confidential pay and passbook integration; did utilize the Local authentication framework for biometric fingerprint scan usage
• Continuous integration handled with Jenkins containing rules to push out builds every morning

Confidential, Reading, PA

iOS Developer

Responsibilities:

• Heavy emphasis was placed on MVVM and decoupling in this project; code reuse was at a maximum and everything was created programmatically
• App was developed to be compatible with devices running iOS7+
• In charge of creating constraints programmatically using NSLayoutConstraints and by way of the visual format language at times
• NSOperations were used for all complex multithreading needs including but not limited to getting points information, popular items to shop, motivational reminders, and the like. Both NSBlock and NSInvocation operations came in to play as well as assignment of priorities for streamlining and optimizing network utilization
• Developed UI using HTML5, CSS3, ExtJS, Bootstrap, JQuery, and JSP for interactive cross browser functionality and complex user interface.
• Used the Node.js, Angular.js, backbone.js and Require.js MVC Frameworks in the development of the web applications
• Implemented user interface guidelines and standards throughout the development and maintenance of the website using DHTML, HTML, CSS, JavaScript and JQuery.
• Got to work with CorePlot for creating line graphs, bar charts, pie charts, and similar
• AVFoundation and MediaPlayer frameworks used for playing of all video material
• Worked on beta versions of iOS and XCode for creation of POC’s on Confidential Watch and working with Swift
• Lightly involved with StoreKit and the in app portion of the application
• Evolving team of 4-6 developers maintained and kept adding features to the app as necessary
• NSCache utilized to mitigate loss of internet connection
• Worked with several 3rd parties like AFNetworking and MBProgressHud which were managed with cocoapods

Confidential, New York, NY

iOS Developer

Responsibilities:

• Main role focused on utilization of mathematical libraries for performing calculations; extensive work done to create a framework capable of easily scaling and being simple to maintain as well as use
• Application developed to be compatible with devices running iOS5+
• Grand Central Dispatch utilized to periodically get/post conversion requests XML data would be parsed with NSXML parser and model objects created for tracking trends and to make predictions
• Created POC’s using push notifications in regards to pre computing conversions for a user based on the location and perceived destination / route
• SQLite was leveraged for storing the most recently retrieved earthquake data, and to ensure functionality when lack of Wi-Fi and cellular connectivity existed; reachability classes were used to determine changing states of connectivity
• Participated in daily standup meetings as part of the agile scrum process, and worked very collaboratively with other developers. We pivoted at times rather sharply within sprints but the team was always very good at taking changing requirements well
• Several categories were created for simplification of commonly used code. For example NSNumber category for signifying metric to imperial system conversions, to go between different variations of measurements, and such were made.
• UITableViews with custom UITableView cells used to portray all calculated information to users in the most efficient and elegant manner possible a wide array of tableview datasource and delegate methods were used
• Performance tuning of the application was done with instruments to ensure no leaks, zombies, or other adverse conditions existed in the app
• SVN used for housing source code and keeping version history

• App UI done programmatically for both iPhone and iPad. Rotation handling was done by registering for UIDeviceDidChangeOrientation notifications and firing a selector that would set appropriate frames for objects
• Back end was JSON and response was parsed using SBJSON NSURLConnection and ASIHTTP utilized
• UIKit framework was used to design and implement user friendly UI
• Memory management system used was Manual Retain Release worked with retains, releases, autoreleases, and autoreleases pools heavily
