Hello there! 👋 I'm Kulla 🧑‍💻

What Drives Me

Driven by Impact. As a software developer, the most rewarding aspect of my work is knowing it genuinely helps others. I strive to invest my finite time, knowledge, and skill to create the greatest possible positive impact for as many people as I can.

Clarifying Complexity. As a mathematician and educator, it excites me to (re)discover the core why behind the curtain of abstraction. I enjoy turning these insights into clear explanations that help others feel that same spark of clarity.

Selected Projects

  • Serlo Editor — Web-based editor for interactive learning materials, designed to help teachers create didactically high-quality content with ease. The key challenge is combining a Google Docs–like WYSIWYG experience with highly structured, interactive exercises—successfully bridging usability and formal structure.
  • The Open Learning Platform serlo.org — Non-profit platform providing free and openly licensed educational resources to enable equitable access to high-quality education. I led a team of up to twelve engineers and helped rebuild the platform using a modern microservice architecture, while also contributing to fundraising and financial planning.
  • Open Textbook "Mathe für Nicht-Freaks" — Open textbook based on the belief that every university student can understand mathematics. It emphasizes intuition and motivation over rote formalism and reaches a substantial share of first-semester STEM students in Germany. A long-term community project and a personal commitment to open education.
