What I'm looking for

I seek remote roles focused on frontend engineering, performance optimization, legacy modernization, mentorship, and strong collaboration with backend teams.

I am an experienced frontend developer with 5+ years building high-performance web applications using JavaScript/TypeScript, React, Next.js, and Svelte. I focus on clean code, performance optimization, and modernizing legacy code while collaborating effectively with backend teams.

At prodexa GmbH I improved UI performance by 30% through lazy loading, memoization, and code-splitting, modernized legacy components to hooks and Svelte to reduce bundle size by 15%, and mentored interns to cut onboarding time by 40%.

My background includes FinTech and PIM/PXM systems, strong backend integration experience with Java/Spring Boot and RESTful APIs, and a commitment to testing, maintainability, and remote collaboration.
