Implemented Data and AI usecases on Snowflake by architecting a cloud data warehouse with ETL/ELT pipelines using Talend and Azure Data Factory, improving analytics efficiency by 30% and translating requirements from 10+ stakeholders into Power BI and Sigma dashboards. Enhanced the Snowflake platform through automated end-to-end workflows using Snowflake Tasks and Streams, achieving 99.9% pipeline reliability from raw ingestion to curated data stores. Leveraged Cloud (Azure, AWS S3) capabilities and applied scalability optimization techniques — Clustering Keys, Materialized Views, and SQL query tuning — reducing average query execution time by 40%. Implemented RBAC, Dynamic Data Masking, and row-level security across data domains to enforce Cloud security, data encryption, access control, and compliance for the Snowflake platform. Applied data engineering principles by designing star schema, snowflake schema, and Data Vault models in dbt, enforcing data quality through dbt tests and CI/CD-integrated documentation. Built data platform integrations ingesting JSON, Parquet, and AVRO from Azure Blob and AWS S3 via Snowpipe and external stages to deliver API-ready datasets.
