Where logic meets creativity and users come first

About Me

Hi! I'm Jennifer Baumgart — a Front-End Developer specialising in React, Next.js, TypeScript, and UI/UX Design with a track record of delivering responsive, accessible, and performance-driven interfaces. My experience spans data-driven dashboards, SaaS platforms, and global marketing websites, always bridging design and code to create user-centred products. With a background in Chemistry, I bring analytical precision and user empathy to every project. I thrive in cross-functional teams, translating complex requirements into intuitive, visually engaging experiences, and I'm passionate about accessibility (WCAG) and inclusive design. Whether crafting a design system, integrating APIs, or optimising performance, my focus is on creating solutions that are as functional as they are beautiful.
