Hoi, I'm Julius

M.Sc. Artificial Intelligence @ UZH | Data Engineer

I am an AI Master's student at the University of Zurich with a background in Statistics and Data Science from LMU Munich. My work sits at the intersection of robust data engineering and advanced machine learning, focusing on Reinforcement Learning, and Time-Series analysis.


πŸš€ Currently...

  • Working at Swissgrid as a Data Engineer, building automated ETL pipelines for energy market transparency.
  • Researching RL with a focus on safety-critical domains.
  • Exploring Meta Learning and Multi-Modal AI agents.

πŸ›  Tech Stack

Category Tools & Technologies
Languages Python, Java, SQL
AI / ML PyTorch, Reinforcement Learning (SPMI, DDQN), NLP (RAG), LSTMs/GRUs
Data Engineering ETL Pipelines, API Integration (ENTSO-E, Wikidata)
Visualization Grafana, Weights & Biases (WandB)
DevOps/Tools Git, Docker, RESTful APIs, CLI Development

πŸ§ͺ Featured Projects

πŸ€– Federated Safe Policy-Model Iteration (F-SPMI)

  • Developed a parallelized variant of the SPMI algorithm for safety-critical Reinforcement Learning.
  • Implemented Gaussian Process-based model selection and UCB sampling to improve exploration efficiency.
  • Built a flexible framework in Python supporting both tabular and neural network policies.

🎬 Multi-Modal Movie QA Agent

  • A hybrid QA system combining Symbolic Reasoning (SPARQL) and Latent Space Inference (TransE).
  • Uses the Wikidata Knowledge Graph to resolve complex natural language queries about the film industry.
  • Features an end-to-end pipeline for entity disambiguation and vector-based similarity search.

πŸ“ˆ Deep Learning for Stock Market Gaps

  • Bachelor Thesis: Comparative analysis of LSTMs vs. GRUs for detecting market volatility.
  • Integrated a Double Deep Q-Network (DDQN) agent to simulate trading strategies in backtesting environments.
  • Utilized WandB for hyperparameter sweep optimization across 1000+ US companies.
