In database development, I focus on designing, implementing, and optimizing databases to ensure efficient storage, retrieval, and management of data. This includes tasks like schema design, creating queries, and managing indexing, security, and backups.
For ETL (Extract, Transform, Load) development, I build processes that extract data from various sources, transform it into a usable format, and load it into databases or data warehouses. I ensure that data flows smoothly, is cleaned, transformed as needed, and stored for analysis or reporting.
