Hi, I'm Matthias.

I'm a software engineer specializing in building web applications. Currently, I'm focused on building my portfolio and exploring new technologies.

Embracing ProseMirror: Why other rich text editors felt like fighting the framework.

Why I chose ProseMirror over Tiptap, Slate, and every other rich text editor — and why understanding the engine mattered more to me than a nice API.

My Journey so far

I've been working as a freelance web developer for the past 2 and a half years. Here's a timeline of my journey.

2023 - Present

Freelance Web Developer

Independent · Remote

End-to-end delivery of client projects - from requirements gathering and architectural decisions through to production deployment, with full ownership at every stage.

Delivered production applications using Next.js, React, TypeScript, and Tailwind CSS; PostgreSQL for data persistence and Docker for reproducible deployments.

Managed deployment and infrastructure independently, including containerization with Docker and performance optimization.

Established structured development practices (component architecture, reusable patterns, maintainable codebases) leading to improved development efficiency and scalability.

2022 - 2023

Frontend Developer

Werbeagentur Höfling GmbH · Würzburg

Developed client-facing projects with a growing emphasis on hand-written code — progressively moving from CMS configuration toward building custom UI components and interactive features.

Collaborated closely with designers and backend developers to deliver responsive, user-friendly interfaces.

Took on increasingly complex tickets over time, marking a clear shift from template-based to component-based development.

Contributed to performance improvements and bug fixing in production systems.
