Andrés Arce contributed to the facebook/react-native-website repository by focusing on documentation quality and contributor experience. During June 2025, he identified and corrected a spelling error in the Contributing Documentation, replacing 'reccomend' with 'recommend' to enhance clarity and maintain a professional tone. Using Markdown and Git-based workflows, Andrés ensured the documentation aligned with project style guidelines and reduced potential confusion for new contributors. His work demonstrated attention to detail in documentation best practices and code review processes. While the scope was limited to a single bug fix, the update reinforced standards for onboarding and maintained consistency across project materials.
