Contributed to amplitude/amplitude-docs by delivering three features over two months, focusing on enhancing documentation and front-end styling capabilities. Worked extensively with JavaScript, CSS, and Markdown to migrate CSS selectors from data attributes to class names, standardize naming with an amplitude-engagement prefix, and clarify Theme beta status for Guides and Surveys. Expanded documentation to provide granular CSS selector coverage for engagement elements and introduced guidance for proxying images via the mediaUrl SDK option, including CloudFront configuration. Incorporated pull request feedback to ensure accuracy and reliability, resulting in more maintainable documentation and improved setup guidance for customers configuring Amplitude’s front-end integrations.
