PROFILE
Justin Wei
Justin Wei focused on enhancing reliability and maintainability for the lichess-org/lila repository, addressing four user-facing bugs over one month. He improved in-game chat warnings to trigger only in losing positions, reducing false alerts and aligning feedback with actual gameplay. Using Scala and TypeScript, Justin fixed stale premove persistence by ensuring moves are only canceled when the board state changes, preserving user intent during reconnects. He also refined sitting feedback logic and led a broad codebase cleanup, consolidating pagination logic into a shared module and improving accessibility. His work demonstrated depth in UI development, functional programming, and software architecture.
