What I'm looking for
I am a Data Engineer and ETL developer with over 7 years in IT and 2.6 years focused on data engineering, ETL and cloud data platforms.

I have hands-on experience building data lakes with Azure Data Lake Storage and Blob Storage, developing scalable PySpark applications, and implementing Snowflake features such as SnowSQL, time travel, cloning and tasks. I integrate diverse sources including Oracle, MySQL, Cosmos DB, HDInsight and Snowflake, and monitor pipelines with Azure Monitor and Log Analytics.
I am experienced in data modelling and data warehouse concepts (star/snowflake schemas), CI/CD-enabled data pipelines and GitHub workflows, and have worked across ETL, data migration, data cleansing and real-time streaming solutions. I seek to apply my technical expertise and practical experience to deliver reliable, high-performance data platforms for analytics and reporting.
