Stefan Perju enhanced the storefront Product Detail Page (PDP) for the hlxsites/aem-boilerplate-commerce repository, focusing on improving product display and user interaction. He delivered version 3.0.0 of the PDP, aligning the interface with the product roadmap and preparing the storefront for future features. Using JavaScript, React, and Node.js, Stefan implemented UI and performance improvements that increased the PDP’s readiness for upcoming milestones. Over the course of one month, he concentrated on feature development rather than bug fixes, ensuring stable delivery without regressions. The work demonstrated depth in front end development and careful attention to maintainability and future extensibility.
