Martin Spier was one of six engineers to take care of all of Netflix Operations about 10 years ago. Back then performance and observability tools weren't as sophisticated and didn't scale to the needs of Netflix as some do today. FlameScope was one of the Open Source projects that evolved out of that period, visualizing Flame Graphs on a time-scaled heatmap to identify specific performance patterns that caused issues in their complex systems back then.Tune in to this episode and hear more performance and observability stories from Martin, about his early days in Brazil, his time at Expedia and Netflix and about his current role as VP of Engineering at PicPay - one of the hottest fin techs in Brazil.More links we discussed:Performance Summit talk about FlameCommander: https://www.youtube.com/watch?v=L58GrWcrD00CMG Impact talk on Real User Monitoring at Netflix: https://www.cmg.org/2019/04/impact-2019-real-user-performance-monitoring-at-netflix-scale/Learn more about Vector: https://netflixtechblog.com/extending-vector-with-ebpf-to-inspect-host-and-container-performance-5da3af4c584bMartin's GitHub: https://github.com/spiermarConnect with him on LinkedIn: https://www.linkedin.com/in/martinspier/
