Do you have experience working with databases: designing, writing SQL queries and scripts?

Yes, I have experience working with databases. In my projects, I was involved in designing database structures, including normalization of tables to minimize data redundancy and ensure integrity.

I also wrote complex SQL queries for data retrieval, updates, and aggregation. For example, I used JOINs to combine multiple tables, subqueries for filtering, and window functions for analytics.

Additionally, I created scripts to automate routine operations such as backups, data migrations, and schema updates. This helped maintain data relevance and integrity within the system.
