I designed and built a multi-source Snowflake data warehouse with Bronze, Silver, and Gold layers, connecting CSV, SQL Server, and REST API data. I used dbt to create dimensional models and tests, then developed a Power BI dashboard with measures validated against Snowflake SQL results.
On DataPilot AI, I built a PostgreSQL pipeline and FastAPI endpoints, and added a pgvector-based RAG layer for schema-grounded NL-to-SQL with query safety guardrails. At Ethara AI, I curated prompts and reviewed model responses for data quality and factual accuracy.
