Ghassen is a true jewel! His data engineering skills and knowledge are amazing. I'm really not sure how he learned so much so quickly. Our data team at Tradeshift was fairly small, with a wide array of tasks. There were several tasks that Ghassen knew and managed that almost no one else touched. I like to ensure that there are always backup skills, when someone goes on vacation, etc. But there was so much that Ghassen did that it was hard to ensure someone could replicate all that he knew and did. For instance, Tradeshift's platform needed a strong indexing solution, so that customers could quickly find any of the documents that Tradeshift processed for them. Ghassen was the sole owner from the data team ensuring this massive task was successful. After his colleague, Abin, Ghassen was the most key player in our conversion from a batch data processing flow into change data capture using Kafka and Delta Lake for managing DB write-ahead log ingestions into our data lake. Despite all of these excellent skills, sometimes Ghassen found himself stuck with several important, but "brain dead" tasks. I could only assume he was frustrated, because I felt bad having to give him these tasks, but he never showed any frustrations. His personality is so calm, relaxed, and generally happy, while also being ridiculously efficient. It was a bit of a joke within the team to see if anyone could get as many Jira board tasks completed as Ghassen consistently managed to complete.
