Charlène Grangy

I’m a Frontend engineer with 5+ years building high-quality user interfaces, grounded in strong React + TypeScript code and a deep attention to interaction details. I’m comfortable owning features end-to-end, from concept to production, while aligning with product, design, and engineering stakeholders.

At Swiss Marketplace Group - Ricardo.ch, I’ve improved key user-facing flows by driving product iterations based on user behavior, feedback, and performance metrics. I’ve contributed to A/B testing and data-driven iteration to help make engagement improvements tangible.

I also helped evolve and maintain a design system to ensure UI consistency at scale, and I delivered reusable UI components that support faster, more reliable product development. I collaborate daily with distributed, English-speaking teams and focus on clear async communication through GitHub, Jira, and Slack.

Previously, I worked in a fully remote agency environment supporting multiple client projects, coordinating asynchronously with designers and back-end developers. I value proactive ownership, efficient collaboration, and code quality through version control and code review best practices.
