EXPERIENCE
Trello — Senior iOS Developer
New York, NY : August 2018 - PRESENT
https://apps.apple.com/us/app/trello-organize-anything/id461504587#?platform=iphone
Worked with Trello for two years to improve on the Boards section of the app, allowing the user to add new Boards, display all of them on a TableView with different headers to separate and organize the Boards, including Starred Boards for any Boards with high importance, and Personal Boards, for solo projects to separate them from team projects for additional organization, with a search text bar at the top of the screen to filter through the Boards. Then once a Board has been selected, the user is brought to a new screen with lists, and each list filled with cards, again on a TableView, and also with a text field search function at the top. Once the user has selected a card from a list, the user will be brought to a final screen with the title, description, due date for time notifications, labels, members list to know who is working on that card, checklist, and activity, displaying a history of what has been changed to the card
-Programmatic and Storyboard design for the elements on each page.
-Attached keys to individual Boards to allow the search function to work.

Money — Senior iOS Mobile Developer
February 2017 - June 2018
https://apps.apple.com/app/id1185488696
Worked with Jumsoft for 18 months fixing and improving features such as the transaction history. The app allows you to separate different bank accounts for you to keep track of payments and help you budget your money. Previously the app displayed the amount added and removed from the account in view but did not display the new total after each transaction, only at the end of the last transaction. Added the total remaining after each transaction in order to provide the user a history of the total within the account.
-Programmatic design for the elements on each account page.
-Organized the transactions by time they were added, with newest at the top.
-Transactions completed on the current day are separated from other transactions, label as Today and Recent.
-After each transaction is added, the total remaining is update and saved along with the other information on that transaction.
-Worked in an Agile methodology with 2-week sprints, daily stand up, monthly releases, and back log grooming.
-Involved in iOS performance testing along with Functional and Regression Tests, Unit Testing, Test Results review and other quality related work.
-Utilized XCTest for unit tests.
