Design modern cloud data warehouse architectures tailored to your analytics needs. Define schemas, partitioning strategies, clustering keys, and access patterns that balance performance with cost-efficiency across Snowflake, BigQuery, or Redshift.
Migrate legacy on-premise data warehouses (Oracle, Teradata, SQL Server) to cloud platforms with zero data loss and minimal downtime. Includes schema conversion, data validation, query migration, and parallel run testing to ensure a seamless transition.
Audit and optimize your existing data warehouse for speed and cost. Analyze query patterns, implement materialized views, tune clustering and partitioning, and redesign slow-performing models to deliver sub-second analytics across terabytes of data.
Build robust dimensional models — star schemas, snowflake schemas, or Data Vault 2.0 — using dbt for version-controlled, tested, and documented transformations. Ensure your models are intuitive for analysts and performant for BI tools.
Implement data governance frameworks within your warehouse: role-based access control, column-level security, data classification, lineage tracking, and automated quality checks that catch issues before they reach your dashboards.
Architect multi-cloud data platforms with cost-optimized compute and storage. Implement auto-scaling, workload management, resource monitors, and FinOps dashboards to keep cloud warehouse spending predictable and aligned with business value.
