Summary

With 8 years of experience as a JavaScript developer, I‘ve focused on Vue and Nuxt for the past 5 years. I‘ve been working with Vue 3 and the Composition API for 3 years. My backend primarily relies on Node servers, and I‘ve recently started learning Rust.

I‘m open-minded and can integrate quickly into new teams. When it comes to coding and technology, I‘m aware and open about my strengths and weaknesses. When I meet like-minded colleagues, we can form very effective teams. I don‘t need a long onboarding process - just a cup of coffee and a friendly team.
