Marlon Richert is a UX Design Engineer with 11 years of experience blending interaction design and hands‑on implementation to ship usable, maintainable products across web, mobile and TV platforms. He architects multi‑platform design systems and frequently prototypes directly in the target app to validate designs with real data, which has let him dramatically reduce mobile codebases while preserving functionality. Comfortable in Vue.js, Sketch/Adobe XD and front-end stacks, he pairs strong engineering discipline with usability research and agile coaching to improve estimates and developer workflow. An active open-source contributor, Marlon has improved popular Zsh tooling—adding async autocomplete and instant prompt features—and enhanced Karabiner complex rules to better support non‑English layouts and terminal ergonomics. Based in Turku, Finland, he prefers remote roles only when a local satellite workspace exists, reflecting his emphasis on collaborative team culture.
