I will write and optimize sql queries for your data analysis

Hi, I'm Jose! I write clean, efficient SQL queries to help you analyze and understand your data. I'm a Data Science and Business student, currently working as a Deals Desk intern at Motorola Solutions, where I work daily with data pipelines, dashboards and SQL-based reporting. What I offer: writing and debugging SQL queries (joins, aggregations, subqueries), query optimization and performance tuning, help with database design and normalization, clear explanations of the logic behind each query, support for MySQL, PostgreSQL and SQL Server. Message me with your schema or sample data so I can scope the work accurately.
