I'm building member-facing health-report experiences and internal operational tools at Noom. I delivered biomarker trend interfaces, interactive health-data visualizations, and localization workflows across four languages.

At Andersen Lab, I modernized a large React ecosystem across 10+ microfrontends, upgrading React, React Router, Next.js, Material-UI, and build tooling. I also migrated legacy Redux services to RTK Query, reducing code by 40%, and moved 15+ services to new GitLab CI/CD infrastructure.

Earlier, I built CV-builder functionality for BewerbungsCode, including drag-and-drop interfaces and real-time PDF generation. I enjoy creating reusable component systems, reliable frontend workflows, and readable data-rich product experiences.
