Sasha Serbin developed and refined user-facing features for SerbynS/project-group-17 and front-band-17/project-wr23-45, focusing on responsive design, accessibility, and maintainability. Sasha modernized UI components, improved navigation with JavaScript-powered menus, and optimized asset management to enhance performance and usability. For project-wr23-45, Sasha implemented a dynamic reviews section using API integration and Swiper.js, added robust error handling, and improved accessibility in the FAQ. Across both repositories, Sasha applied CSS and HTML to standardize layouts, resolve rendering issues, and ensure consistent, production-ready interfaces. The work demonstrated depth in front-end engineering, balancing new feature delivery with systematic bug resolution.
