Summary
🤩
Rockstar🎓
Top SchoolJosefina Mancilla is a creative, user-focused software engineer with eight years of experience building polished front-end experiences, currently developing at H-E-B in Austin. Previously she was a key front-end contributor to IBM’s Carbon Design System, shipping UI components, accessibility fixes, and design-token improvements used across IBM products and the popular carbon-design-system repos. She blends strong visual sensibility (rooted in a journalism and content background) with practical engineering: refactoring components, solving responsive/layout issues, and adding interactive pieces like GifPlayer and improved navigation. Comfortable across the stack from prototypes to production, she’s prized for bridging design and code and for quietly improving developer UX in design-system tooling. Off the clock she’s motivated by small, tangible goals—like giving her dogs a better life—which reflects her pragmatic, empathetic approach to engineering.
