### About me I’m a **Staff-level Frontend and UI Engineer** with **13+ years of combined professional and teaching experience**, specializing in **UI engineering**: Design Systems, enterprise CSS, responsive layouts, accessibility (WCAG), data visualization, and web animations — with deep expertise in **React, JavaScript/TypeScript, HTML, and CSS**. Throughout my career, I’ve consistently operated as **the bridge between Design and Engineering**, translating ambitious visual and UX goals into **scalable, performant, and accessible frontend systems**. My work focuses on aligning design intent with real-world engineering constraints while maintaining long-term maintainability and code quality. I’ve led and contributed to **Design System initiatives**, built **data-visualization–heavy charts, tables, and UIs**, improved **localization workflows**, and helped raise **UI standards across critical user flows** in large, high-impact products. A recurring part of my work involves **untangling legacy stylesheets** and transforming them into **clean, enterprise-grade CSS and component architectures**. In addition to hands-on engineering, I bring **5.5 years of experience as a Udacity mentor**, where I guided developers through frontend, UI, and JavaScript projects, reviewed real-world codebases, and helped engineers progress from fundamentals to **production-ready practices**. I mentor because I enjoy helping developers move beyond surface-level fixes and truly understand **why UI breaks** — whether it’s layout mechanics, rendering behavior, accessibility pitfalls, or component design.
