I worked on the development of RedKiwi, a YouTube-based English learning app serving 1M+ active users worldwide.
* Stack: TypeScript, React Native, GraphQL, Firebase, Node.js, Elastic Search, Redis
* Developed the streak feature that increased 1-day and 4-7-day retention by 11% and 8%.
* Co-developed Word Map feature that visualizes the words users learn watching videos. It became a backbone feature of the app.
* Co-developed Mission Words feature that encourages users to find specific words in a video. It grew full video views by 13%.
* Proposed, designed and started development of the Fan Vocabulary feature that encourages users to find words on a given fan topic (e.g. Harry Potter, Star Wars) across all videos
