Project History
BoredPanda application
https://apps.apple.com/us/app/bored-panda/id1001593357A Swift-based iOS application for the popular online magazine Bored Panda.
I've contributed to the project as an iOS developer and worked closely with the back-end team on designing data structures and API endpoints the application would be consuming. Moreover, I worked with UI/UX designers and helped them create the application UX with a native iOS feeling. Developing a mechanism for natively rendering journal posts was challenging because the content was first designed for websites, but we've accomplished it.
