Principal Observability Architect at Sage
Joana has been a performance engineer for the last ten years. She analyzed root causes from user interaction to bare metal, performance tuning, and new technology evaluation. Her goal is to create solutions to empower the development teams to own performance investigation, visualization, and reporting so that they can, in a self-sufficient manner, own the quality of their services. Currently working at Postman, she mainly implements performance profiling, evaluation, analysis, and tuning.
