Worked on the mercadopago/devsite-docs repository to enhance Nuvemshop integration guides with multi-language support, focusing on English, Spanish, and Portuguese documentation. Applied a documentation-driven approach using Markdown, aligning content across languages for consistency and maintainability. Incorporated feedback from code reviews to improve clarity and structure, ensuring that updates were reflected in all relevant guides. The work prioritized developer onboarding and streamlined the integration process by making guides easier to follow and maintain. No bugs were fixed during this period, as the primary contribution centered on feature development and localization, resulting in improved accessibility and faster time-to-value for developers.
