🧠 About Me

I'm a Data Scientist and ML Engineer currently pursuing my M.Sc. in Data Science at TU Hamburg (TUHH). I love building end-to-end ML systems — from raw data pipelines to deployed models — and I'm equally comfortable on the backend infrastructure side.

  • 🎓 M.Sc. Data Science @ TUHH, Hamburg (2025–2027)
  • 💼 Previously at BISAG-N (geospatial ML) and Motadata (real-time ETL & event-driven systems)
  • 🏆 Hackathon winner — NiT Sparkathon 2025, Hamburg
  • 🌱 Currently exploring real-time ML systems with Kafka, Flink, and stream processing
  • 🌍 Based in Hamburg, Germany | Open to Werkstudent roles (20 hrs/week)
  • 🗣️ English (C1) · Deutsch (B1, actively improving)

🛠️ Tech Stack

Languages Python Java Go SQL R
