Hi, I'm Jonathan Bungay. I am a Senior Data Warehousing consultant with expert Teradata database knowledge and over 22 years of administration and development experience. As a current Teradata employee, I have consulted with large retailers, telecommunications companies, and small financial clients, taking on roles such as DBA, developer, physical data modeling, performance tuner, and mentor. I thrive in team-oriented settings but am equally comfortable working independently. I focus on establishing data warehouse standards, building tooling with stored procedures and TTU, and enabling teams to deliver scalable, reliable data warehouses. I regularly support BI tools like MicroStrategy, Qlik, and SAP BO, collaborate with ETL teams, and continuously tune performance to maximize throughput and data quality.
