Zachary Ryan

Zach graduated from the University of Hull with a BA degree in Philosophy, Politics and Economics. Although not facing any data analysis at university, he found that he enjoyed analysing in general and saw the natural progression of this would include data.

After scrolling the job boards for a while and finding the opportunity with the Data School, Zach applied and in the application process found that he really enjoyed working with Tableau. Since joining the Data School, Zach has found enjoyment in both Tableau and Alteryx, achieving certifications like the Certified Data Analyst for Tableau and the Core and Advanced certifications for Alteryx.

Having consulted for Solar Turbines, Zach helped with the migration of Alteryx workflows to Matillion, utilising the likes of SQL and AWS to do so. In addition to this, Zach made multiple Tableau and PowerBI dashboards, analysing expenditure and identifying areas for optimisation within the business.

Currently consulting for PwC, Zach works with both Alteryx and PowerBI, providing services for the firm internally to help complete tasks for teams to report back to their clients, as well as running training sessions to help upskill other members of the company.

Out of office, Zach enjoys watching sports, most commonly Football and F1, and performing strongly in both... in their video game counterparts. Outside of that, he enjoys spending time with friends and trying the cuisines (and attempting to recreate them) that both London and the world have to offer.

An Introduction of Snowflake Semantics
With Snowflake being one of the services you'll look at in the DS beside Alteryx and Tableau, I thought it'd be worthwhile to inform the people of some of the more basic prompts used on the service. Take a look!
