Look inside

Master the basic methods for handling most real-world scenarios as you play the role of a data scientist in an online recruiting tech company or a large organization’s HR department. Using pandas, you’ll process, extract, and transform numerical, categorical, time series, and text data into structured features that are ready for data analysis and ML model training. When you’re done, you’ll have hands-on experience working with most data types you’ll find in the real world, as well as useful skills for extracting and engineering features.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book resources

When you start your liveProject, you get full access to the following books for 90 days.

Ruihao Qiu

Ruihao Qiu is the senior data scientist at a German tech company and has more than five years experience in data science and machine learning. As part of the process of earning his PhD in statistical physics, he developed statistical models to simulate and search for new nanomaterials. In his early days as a data science consultant, he helped his clients from DAX30 multinational companies solve real-world data challenges. As a senior data scientist, he designed and built data pipeline and ML recommender systems for online recruitment applications. He enjoys taking on different career roles and sharing ideas about his data science work in tech blogs and in public presentations.


This liveProject is for Python beginners interested in learning feature extraction and engineering using pandas. To begin these liveProjects you’ll need to be familiar with the following:

  • Basic Python
  • Basic Jupyter Notebook/JupyterLab
  • Intermediate pandas
  • Basics of regular expressions
  • Basics of trie data structure
  • Basics of data types

you will learn

In this liveProject, you’ll learn commonly used methods for feature engineering in machine learning, as well as how to clean, transform, normalize and encode different types of data.

  • Use built-in Python modules
  • Use pandas for various dataframe operations
  • Methods for the Trie data structure
  • Methods for dealing with different datatypes (numerical, categorical, time-series, and text)


You choose the schedule and decide how much time to invest as you build your project.
