My name is Justin Matters. I am a data scientist, programmer, board gamer, martial artist and general geek. I currently work in data science and machine learning for QueryClick in Edinburgh in the UK. I currently produce big data pipelines in PySpark including Machine Learning with Spark ML and MLlib. I have experience with a variety of cloud technologies on Azure and AWS. I have extensive experience of SQL working with Azure SQL and Apache Druid. I also have a strong knowledge of data science techniques in Python including libraries like Pandas, Matplotlib, Seaborn, SciKit Learn, OpenCV, Tensor Flow and PyTorch. I experiment with LLMs, mostly locally hosted via Ollama. I also create graphics and animations using Blender, GIMP, ComfyUI and a variety of other open source packages.
