I am a software engineer experienced in developing/operating data driven applications running on public clouds. I currently work at Pure Storage. In the past I led migrating a science platform to AKS and led establishing containerization and DevOps practices in a data team at Turbine.ai. Before that, I worked on data pipelines running in k8s at Hiya. Previously, I developed the main social database ingestion pipeline, and the credit fraud detection ML training pipeline at Ekata. I hold an M.Sc. in Computer Science Engineering.
