Back to original languageAbout Jed
Performance architect with over 20 years of experience, I am involved throughout the application lifecycle: during the build phase, I contribute to architecture design and performance validation through load testing. During the run phase, I set up monitoring tools and dashboards to ensure optimal performance tracking. During crisis phases, I intervene as an emergency responder to diagnose problems, propose immediate workarounds, and recommend medium and long-term actions to permanently resolve bottlenecks.
