What I'm looking for

I'm looking to further develop my career in digital marketing and UX/UI design, applying SEO, Google Ads, UX principles, and AI-powered tools to improve customer experiences and support business growth.

I've built digital marketing strategies for Zweirad Kretke, a German bicycle retailer, using market, competitor, and keyword research to identify growth opportunities. I optimized its Google Business Profile, created its LinkedIn business page, and planned local SEO and Google Ads strategies.

I've also designed responsive interfaces and interactive Figma prototypes for clients in Chile and Germany, translating business needs into user-centered concepts. My customer-facing work has strengthened the communication, problem-solving, and customer-first mindset I bring to digital experiences.
