About Andi

I am an experienced freelance frontend engineer from Munich, currently living in Trier. I specialize in modern frontend technologies such as React.js, Next.js, TailwindCSS, and TypeScript. Active in the developer world since 2015, I have over eight years of expertise – four of which have been as a freelancer since 2019.

Together with my project partners, I aim to sustainably improve projects through qualitative, performant, and clean code. My approach is to always act results- and solution-oriented, while maintaining open and honest communication – as this is the only way we can achieve peak performance together.

My core competencies:

- Frontend Engineering: Extensive knowledge in React, TailwindCSS, Next.js, and TypeScript.
- JAMStack: Experience in developing fast, secure, and scalable web applications.
- Test-Driven Development (TDD): Familiar with tools like Jest, Karma, and Jasmine.
- End-to-End (E2E) Testing: Expertise in Testcafe and Cypress.
- Mobile UX/UI: Special focus on optimized, responsive designs for mobile devices.

If you are looking for a reliable, proactive, and experienced frontend engineer with a focus on React and Next.js, I am ready to take on the challenges of your project. I look forward to working with you! 👋🏻
