Nazneen Jafri has spent nearly two decades in the trenches of large-scale production environments, developing an instinct for the kinds of problems that only surface when systems are under real pressure. Her career has spanned hands-on infrastructure and technical leadership at JPMorgan Chase and Ford Motor Company — where she built deep expertise across Crunchy PostgreSQL, GCP Cloud SQL, and large-scale enterprise platforms — to engineering and leadership roles at AWS, where she led the RDS and Aurora PostgreSQL team as Engineering Manager before returning to her first love: the deep technical work of understanding how databases actually behave in production. She currently focuses on RDS and Aurora PostgreSQL internals, performance, and contributing back to the open-source community. When she's not chasing down obscure storage-layer and performance edge cases, she's probably thinking about the next one.
