• Proven experience building event-driven and streaming data integrations at scale.
• Expert knowledge of Azure data services (ADLS, ADF, Databricks, Event Hubs).
• Strong experience implementing and maintaining CI/CD workflows (Azure Pipelines, GitHub Actions, ArgoCD).
• Production experience deploying and managing containerized services in Kubernetes (AKS preferred).
• Experience with data quality frameworks and testing tools (Great Expectations, Soda, dbt).
• Knowledge of data governance tools and metadata management (Unity Catalog, Purview).
• Experience with infrastructure-as-code (Terraform, Bicep) and platform engineering.
• Understanding of feature engineering patterns and data preparation workflows for ML systems.
• Background in system design, performance optimization, and capacity planning for data platforms.
• Contributions to open-source projects or technical community involvement.
