Dylan Petrusma – Database Administrator


I have been working with SQL Server at Youi Insurance since June 2014, first as a BI analyst and now as a DBA. I have experience in writing queries, performance tuning, creating reports, database monitoring, and implementing DevOps in this financial services organisation, and I am always trying to learn more about improving our use of Microsoft SQL Server products.
