Could you introduce yourself and describe your roles and responsibilities in your projects?

I am a data engineer with 4 years of experience building end-to-end data pipelines. In my most recent project, I worked on a retail analytics platform. My responsibilities included designing the data ingestion layer, writing Spark jobs to transform raw logs, and loading the results into a Snowflake data warehouse. I also collaborated with data scientists to create feature tables and with product managers to define reporting requirements. I used Delta Lake for versioned storage, implemented data quality checks with Great Expectations, and automated the workflow with Airflow. The result was a 30% reduction in data latency and a 25% increase in query performance for the business intelligence team. I also mentored junior engineers and documented best practices for the team.
