Back to original languageAbout Matthias
Front-end developer with over 4 years of experience, I design fast, clear, and results-oriented web interfaces. My goal is not just to develop, but to concretely improve your product's impact: performance, conversion, and user experience.
Specializing in React and Next.js, I work on projects where execution quality and speed are key. I assist with both the creation and improvement of existing products, with a pragmatic and business-oriented approach.
I regularly work on:
- Development of modern and performant interfaces
- Creation of optimized landing pages (SEO & conversion)
- Performance optimization (Core Web Vitals, loading times)
- Front-end redesign or UX improvement
- Quick integration of mockups (Figma → production)
My approach:
Quick understanding of needs, focus on the essential, clear communication, and efficient delivery. I favor simple, robust, and directly useful solutions.
I primarily work on short or focused missions (a few days to a few weeks), ideal for unblocking a situation, improving a product, or quickly delivering a feature.
Main stack: React, Next.js, JavaScript / TypeScript, HTML / CSS
I can also work on WordPress or Shopify depending on the needs.
If you are looking for an autonomous developer, capable of understanding your product and quickly delivering concrete results, I can effectively support you.
