Experience
Full-stack Developer (Working Student)
-
Fraunhofer Institute for Open Communication Systems
At Fraunhofer FOKUS, I served as the primary web developer on a LIDAR scan visualization tool for internal research, owning the web architecture, API design, UI redesign, error handling, and resilience. I authored technical documentation for 2+ years of legacy code and developed an automated validation platform for architectural submissions, replacing a manual email-based workflow.
Education
2023 - 2025
Master of Science — Computer Science
Technical University of Berlin, Berlin
Grade:
1.1
My studies at TU Berlin focussed on modern Web Technologies, Computer Graphics, and Artificial Intelligence. Working at Fraunhofer Fokus, I gained practical experience in these fields, and put it into practice in my master thesis about a neural indoor localization pipeline using synthetic training image generation.
2022-2023
Language School
KAI Japanese Language School
After my Bachelor’s, I spent a year studying Japanese at KAI Japanese Language School in Tokyo. Finishing the general course after 4 terms, I achieved CEFR B1-B2 Japanese Language proficiency, enabling me to live independently in Tokyo.
2018 - 2022
Bachelor of Science — Informatik
Christian Albrecht Universität
Grade:
1.8
My Bachelor’s at CAU Kiel was focussed on building a ground-up fundamental understanding of practical and theoretical Computer Science, including essential courses on computational theory and systems design. I minored in education, and took Japanese courses as an elective during the COVID pandemic. In my thesis, I explored radiosity-based global illumination precalculation for use on low-spec machines.
