Hyunwoo Lee

Worked on two major features across facebook/react-native and githubnext/discovery-agent__facebook__react-native, focusing on automation and developer tooling. Delivered a Kotlin DSL for building nested bridge payloads, introducing builders like buildReadableMap and buildReadableArray to reduce boilerplate and standardize data structures in React Native bridges. In parallel, implemented end-to-end UI testing for the FlatList component, automating app launch, scrolling, and interaction verification to expand regression coverage and reduce manual QA. Leveraged Kotlin, JavaScript, and Maestro for these solutions, emphasizing automation, reliability, and cross-platform consistency. No bugs were fixed during this period, with work centered on feature delivery and process improvement.

October 2024 monthly summary for githubnext/discovery-agent__facebook__react-native. Delivered end-to-end testing coverage for the FlatList component in the React Native tester app. Implemented an automated test that launches the app, scrolls to item_600, and verifies interaction by clicking a button. Commit 667ba76aefa3e52643683ae70aa6a8f74200d1d7 documents the change ("Click basic button & scroll down until item 600 is visible (#46804)"). No major bugs fixed in this repo this month. Business impact: tighter regression coverage for UI behavior, reduced manual QA time, and lower risk in releases. Technologies demonstrated: React Native, end-to-end UI testing, automation scripting, and commit-based change traceability.
