Examples of My Previous Data Analysis Projects

I’m proud to have helped many businesses make sense of their data and use insights to improve processes. Data analytics is a broad field, with many business benefits, but exactly how I apply data analytics to businesses depends on their unique requirements. Here are some examples of how I have implemented data analytics to the businesses of past clients:

  • Using Python (Pandas), designed ETL processes to improve the efficiency of extracting data from various sources, transforming it into a common format, and loading it into a SQL database.
  • Using statistical methods and queries, constructed models to benchmark and carry out a cost-benefit analysis of third party inventory suppliers.
  • With data science and machine learning techniques (Scikit-Learn, NLTK, Spacy), developed advanced name mapping and lookup tools to match variations of client names to their unique parent company.
  • Using ServiceNow, wrote scripts for a business to help them efficiently calculate and display KPIs for IT performance analysis.

One of the smartest people that I have worked with

Jacek is one of the smartest people that I have worked with. His ability to provide huge swathes of in-depth analysis are impressive to say the least and his brain is seemingly able to compute huge amounts of data whilst his Excel skills are second to none. He is also a really great guy and I am confident that he would be an invaluable asset to any company.
