Maciej Marek - Data Science @ PMI – Journey from business problem to the data product industrialization

Have you ever wondered what is behind the choice of products available on the store shelves? Why at a given airport you can buy different products than at the train station? During our speech, we will present techniques and tools (such as Kubernetes, Docker, Airflow) that we used during the project dedicated to the optimization of the product catalog at Philip Morris International. We will tell you how data science works in a global organization like PMI and share our best practices on how to create and implement Data Science products in production environments.

So how to use the graph database (Neo4j) to analyze the community based on the content of your mailbox, with the help of algorithms such as "clustering coeffcient" or "strongly connected components".

I invite you to an expedition to the world of graphs, during which we will look at graph theory and the Neo4j database. After a short theoretical introduction, we'll learn about Cypher, its syntax, data types, and the basics of graph modeling. We will build, materialize and traverse small and large graphs based on the content of my mailbox. We will learn algorithms and techniques for analyzing social networks.

Maciej Marek

Enterprise Data Scientist, CI/CD best practices evangelist, and trainer @ Philip Morris International. He is passionate about Big Data building blocks, Spark lover and Machine Learning enthusiast. His primary interest is to answer the question: how can we create entire data products with AI core inside from data collection to web application?

Jarek Pałka

For more than 20 years in the IT industry, as a database administrator, programmer, architect, manager and "onsite disaster engineer". At the moment, working at Neo4j as performance engineer, enjoying the way of code, and exploring dungeons of JVM and OS, after few years as chief architect in SaaS business and teach lead in I took part in small, medium and large projects nonsense, under the principles of "Waterfall", Agile and in the absence of any methodologies, always with the same effect. What led me to the conclusion that no matter what you do, as long how you do it well, in the simplest possible way and use appropriate tools that do the work for you. In the meantime, I fell in love in the ideas of TDD and Software Craftsmanship, to the limits exploring beautiful in its simplicity ideas as REST and NoSQL, only to abandon them to explore the secrets of "systems thinking" and admire the strength that brings "metaphor" and discover that we are all objects in an eternal virtual machine. A humble follower of the church of JVM, bytecode and JIT researcher, exploring all sorts of parsers, interpreters and compilers.

From time to time you can hear my low-quality jokes about architecture conferences in Poland. I am also the author of a blog on and self-proclaimed dictator in the program committee at SegFault, CoreDump, 4Developers and JDD conferences.
