With 15 years of experience in performance testing in Linux environment on various technologies (Java on Was/Tomcat, DB on Oracle, deployed on legacy, PCF, Kubernetes) I was able during these years to help projects to set up their test environment, create scenarii to load their application (Soap, REST, HTML, JMS) but also to help them to improve the slightest little slowdown in order to have a reactive application whatever the load. To facilitate product team tests, I participate to set up and maintain Self Service Portal in JAVA/VueJS based on Jenkins, Jmeter, Wiremock for the load test and mocking part, and on grafana/InfluxDB/Prometheus for the metrics part.This allows dev teams, without having any particular knowledge in JMeter, to quickly set up test cases and to make them autonomous on this part (Self-Services).It is naturally that today I act as a Site Reliability Engineer (SRE) in order to analyze the production incidents, propose continuous improvement on DEVOPS processes but also put in place KPI to anticipate issues in LE.I'm also force of proposal to eliminate time-consuming, manual, repetitive and non value added process to give people their right place in each team.
