Über mich

I have excellent knowledge of building performant React.js applications with TypeScript and an in-depth understanding of frontend technologies. Due to my background, I provide solid complementary solutions for backend services such as GraphQL in combination with AWS, including websites and platforms, Smart-TV, and In-Car applications.

What sets me apart is my proactive approach to teamwork. I believe that communication, transparency, and learning are key to building high-quality solutions, next to reasonable application testing. I thrive in environments where I can take responsibility and drive projects to completion. I love generating ideas that span design, functionality, product enhancement, and organizational efficiency. When you work with me, you're not getting a coder; you're getting a partner who accelerates your ideas from concept to reality. Whether bringing your innovative ideas to life, troubleshooting existing challenges, or enhancing your current solutions, I look forward to contributing my skills and enthusiasm to your team.

Let's create something together.
