Work Experience

iOS Developer

2022 - 2022

Yonder AG

Developed Yonder Reader, a document reader app designed to handle gigabytes of data. The company was already working on a new app version when I joined Yonder.
Led the effort to improve the app's performance and clean up the codebase. I improved the app's performance 10x, fixed multiple memory leaks, and added unit tests.
Shared my knowledge and best practices with other engineers to help the team avoid common pitfalls and maintain code quality in a fast-paced development environment.

Software Engineer

2017 - 2021

Facebook

Worked on the UI components library similar to UIKit. Created multiple UI components with custom animations and event handling. This library was used internally by multiple teams.
Created unit and integration tests for every element in the library. These tests used Meta's CI tools to monitor and report any issues.
Collaborated closely with client teams and QAs to continuously gather feedback and improve the components mentioned above.
Worked on a project where I created TextView from the ground up using C++ and Meta's proprietary graphics and system libraries.
Created bots to monitor the performance metrics of TextView continuously. These bots would alert me if anything caused a regression in TextView performance.
Planned and tracked multi-month projects by creating bite-sized tasks, which made it very easy for my managers and me to track progress and better understand the project's state.

Bank of Georgia

Developed the Bank of Georgia application for iOS. I was an integral part of the development. Implemented multiple screens for managing user accounts.
Worked closely with designers to come up with fluid animations and easy-to-use UI.
Handled an internal app independently for ride-sharing. Using this app, bank employees could carpool to and from work.
Collaborated with back-end developers to create appropriate REST APIs and implement push notification services.

Experience

iOS Applications

http://bit.ly/3wqaxty

I worked on various iOS applications for different companies, using multiple iOS native libraries and REST APIs. I was always able to create custom UIs based on provided designs. Every time I needed to learn new APIs, I was able to ramp up quickly and use them accordingly.
