Johhed15/README.md
  • 💻 Currently working as a Data Engineer, building and improving data pipelines, data platforms, and cloud-based data solutions.

  • ☁️ Working primarily with Microsoft Azure, Microsoft Fabric, Databricks, PySpark, Python, R and SQL.

  • 🤖 Experimenting with AI-first coding, with the goal of making AI my primary interface for writing code.

  • 🎓 During the spring of 2025 I wrote my Master Thesis on the effects on model performance and CO2 emissions when using representative subsets, if you want to learn more about it, it can be found here: link.

  • 📊 I wrote my bachelor's thesis about a mixed media model designed to analyze the effects of money spent on each channel in acquiring new customers. The model used for this analysis was XGBoost with various variable transformations to capture carryover effects and seasonal patterns, SHAP values were employed to achieve a more fair assessment of each channel's contribution

  • 🧩 Enjoy solving problems with data, whether through data engineering, analytics, or machine learning.
