Lead Developer Java Performance Monitoring at Datadog

Douglas Hawkins has been passionately developing software for the past 20 years.
Throughout Doug's career, he has focused on creating performance intensive applications
in Java ranging from bioinformatics to financial exchanges.

After 10 years as a Java developer, Doug transitioned to working on Azul's Java Virtual Machine.
Today, Doug continues his interest in building performance tools for developers working on Datadog's Java Application Performance Monitoring.

While Doug's passion for developing software remains, his true passion is in sharing his
interest in low-level details and JVM performance with others.
