Di Liu is a seasoned front-end software engineer with 15 years of experience building consumer-facing products and creative tooling, now based in New York City and returning to work after an extended medical leave. She was a primary engineer on Google Photos for Android (helping scale it to hundreds of millions of daily users) and led development of the Paint editor for Scratch 3.0, contributing to a platform used by tens of millions of kids worldwide. Her strengths lie in complex UI, SVG/WebGL rendering pipelines, and integrating rich graphic editors into large React codebases. Beyond code, she brings a strong visual design background—art directing the MIT Mystery Hunt 2021 and contributing art to multiple puzzle hunts and MIT events—which informs her UX-sensitive engineering. Currently focused on reconnecting with NYC engineering opportunities, she’s been keeping sharp with ongoing programming and indie game art projects during her time off. Her rare combination of production-scale mobile experience and deep front-end graphics expertise makes her a great fit for teams building creative, media-rich applications.
