Enhancing your data team with ours
Our consultants come armed with both technical and soft skills to support you to make the most of your data.
The Data School has been paramount to our success at JLL. It has allowed us to bring in highly skilled Tableau and Alteryx consultants. It saves considerable time trying to recruit contractors as I know their skills and training are to the highest standard. Over the past 5 years my team has developed analytical insights which have generated multi million dollar savings of which a considerable amount can be attributed to the Data School consultants we have had working on projects.

Programatically Generating dbt Model Files Using Python
For a recent dbt migration project for a client, I built a macro that generated SQL for models based on a seed configuration table. While this approach saved time, I wanted to take my workflow a step further by automating not just the SQL generation itself, but also the creation of the .sql files
