Back-end Developer
Back-end DeveloperContributions:9 releases, 2 reviews, 105 commits in 4 years 6 months
Contributions summary:Marios primarily contributed to the `frameless` project, which focuses on expressive types for Spark. Their work involved upgrading dependencies like Cats to version 0.7.2 and extending projections to handle ten dimensions. Furthermore, the user added a method to create a TypedDataset from a Spark DataFrame, implemented aggregation and projection functions, and introduced the support for several utility functions like explode(), flattenOption() and asCol(). The user also adapted the functions to work on both projected and aggregated columns.
