Experience on the MX Data Lake learning project, such project has the objective of improving technical skills. During that period, i developed queries for new table formation using AWS Athena as well as new dashboards with PowerBI, those new dashboards facilitated the understandment of the big amount of data for managers, heads and directors. Also, i brought new features, implemented Row Level Security (RLS) systems for existing dashboards, and remade dashboards that did not facilitate the visualization and understanding of that data.
