Lei Ma

Halo! I’m Lei Ma. I am a physicist transformed data scientist based in Germany. I am a theory-centric data scientist with well-trained engineering skills. Apart from developing and productionizing deep learning models in my work, I regularly organize online discussion groups to keep track of the progress of machine learning. As for my engineering skillset, I worked on data warehouses and data lakes, model building, statistical and deep learning model deployment, and machine learning API for production. Nevertheless, my specialty is bringing the value of deep learning models to various industries.

Developing a career, I am focusing on forecasting with deep learning. I worked on marketplaces for housing, logistics, and fashion ecommerce. I worked on products that optimizes marketplaces using data driven models which helps us build a more efficient and environmentally friendly future. And now I am working in chemical manufacturing. In general, I love the notion that machine learning improves the quality of our lives.

I am also a maker. I’ve built a bunch of fun stuff in my free time, most of which are open source as I am deeply attached to philosophy of Free and Open-Source Software. I am also a reviewer of the Journal of Open Source Software and PyCon DE & PyData.
