spiega tech

Spiega is a collection of articles/post written during 17y of career spanning over 3k3 source code files and 2k images. The main areas are around data science and the impact of using machine learning in operations and business. Some content is presented as slides or as automated generated summary in the overview page. For a more business oriented description of those activities refer to .

During this time I tried to make the organize the diverse topics into some main areas which are:
