As a CTO I'm responsible for our product & engineering, technical infrastructure and databases - we use MySQL & PostgreSQL. Prior to joining HotelQuickly I spent 4 years working as a data warehouse consultant, developing and optimising data marts running on Oracle.
I'm passionate about databases, ETL tools, business intelligence (BI) solutions and new trends in software development.
Here on Udemy I run a course "Practice advanced SQL queries with MySQL 5.7+"
