ABOUT SI GAO
As a Senior Data Engineer with 10+ years of hands-on experience in the Insurance, Banking, and Real Estate industries, I excel at managing complexity and ambiguity while constructing end-to-end data solutions, which includes data pipeline design, ETL processes, data warehousing, and advanced analytics. I\'ve designed, developed, and maintained robust data ingestion pipelines using RESTful APIs, and have employed data manipulation languages like Spark, SQL, and Python to handle large volumes of data.My experience extends to designing and developing Modern Data Warehouse Architectures with tools such as Azure Databricks, Google BigQuery, and Amazon Redshift. By utilizing ETL tools like SSIS, Azure Data Factory, Alteryx, and Fivetran, I ensure the quality and integrity of data throughout its lifecycle, managing various data formats including JSON, Parquet, AVRO, CSV, BIN, XML, and EXCEL. I\'ve successfully implemented data warehouse on both on-premise databases and cloud platforms under Agile/Scrum software development practices.In the realm of data visualization, I have crafted insightful dashboards using Tableau, PowerBI, and Looker. This skill enables me to translate complex data into easily interpretable visuals for decision-makers.With a holistic understanding of the data lifecycle, I\'ve excelled in troubleshooting across all stages of the data pipeline. My expertise in data engineering has consistently contributed to data-driven decision-making and business growth.
