Hi, I’m David

Data Analyst Degree Apprentice · Mercedes-Benz UK  |  BSc Digital & Technology Solutions (Data Pathway)  |  Future Data Scientist

I build with data. Focused on real-world problems in the automotive industry and in healthcare — turning messy, complex datasets into decisions that matter. Currently deepening expertise in machine learning, data engineering, and statistical modelling.


Currently Working On

  • Expanding my knowledge in Python, SQL, and Machine Learning.
  • Exploring my creative side through content and storytelling.
  • Working on personal projects that explore data visualisation, predictive modelling, and automation:
    • 🔬 Predictive Maintenance — Engine failure prediction using NASA CMAPSS turbofan dataset
    • 🏥 NHS A&E Analytics — Waiting time trends and capacity analysis using public NHS data
    • 🧱 Data Pipeline Architecture — Medallion architecture (Bronze → Silver → Gold) on Databricks
    • 🌐 Personal website (minimal, clean, self-hosted)
