This publication is a compilation of business problems that I have tackled throughout my career, with a focus on simple solutions. Its purpose is to share my experiences, thoughts, and high-level recommendations with those interested in pursuing a career in this field.

While this material does not delve deeply into implementation details or the use of recommended tools, ample documentation is available online.

My objectives in creating this material are threefold, and I hope to achieve at least one of the following:

  • Debunk the notion that a PhD-level expertise in neural networks is necessary to succeed as a data scientist and solve significant business problems.

  • Share simple solutions that have successfully addressed major business problems during my career, with the aim of inspiring others.

  • Publish this work in the hope of transitioning from a traditional corporate career to a more flexible lifestyle that combines my passion for long-term travel with my passion for data science and machine learning. I am currently available for advisory opportunities with startups or large companies in this field. If you believe that we can collaborate, please do not hesitate to connect with me on LinkedIn (@alankrumholz) or send me a message.
