Summary

I develop modular, scalable, and high-performance web applications based on well-thought-out architectures. In the backend, I offer solid expertise in PHP, Python, and Node.js. With this, I implement server-side rendering or robust API layers and integrate databases as well as other third-party systems. With an eye for detail, I put special emphasis on user-friendly UIs that focus on accessibility and progressive enhancement.

Thanks to broad practical experience from diverse collaborations, I help my clients understand technical challenges and make informed decisions. I provide strategic consulting and develop future-oriented, sustainable solutions that align with your long-term goals.

With experience in frontend, backend, operations, business, and design, I bring a holistic perspective to software product management. I focus on agile methods like Scrum and Kanban, prioritize lean approaches and clear requirement analysis.

Driven by a passion for learning and teaching, I offer hands-on coaching in web development, from the fundamentals to modern tools like React and Next.js.
