Hi. I’m Stefan, a front-end developer from Germany.

My focus is on HTML, CSS, Accessibility and Progressive Enhancement. When I use JavaScript, I like to limit myself to browser APIs whenever possible.

The web has come a long way. Features that used to require libraries or frameworks can now easily be implemented using vanilla JavaScript.

Such an approach keeps the codebase small, avoids bugs, and improves the performance.

Since 2004 I have been working in this business.

Stefan has been supporting the company for years. He played a key role in developing our front-end further and always delivered on time and with great additional ideas.

I would definitely work with Stefan again and can highly recommend him.

I have worked with Stefan on front-end projects for over ten years. His work was always done on time, on budget, and with a high degree of professionalism.

It’s obvious he takes tremendous pride in his work, and I wouldn’t hesitate to recommend or work with him again.
