📖 Description

SQL is the backbone of my data analysis and reporting work. With MySQL, I can directly access, structure, and transform raw data into clean, decision-ready insights for finance and business.

From data extraction and transformation to query optimisation and reporting, these projects show how I use SQL to:

• Build and query financial databases
• Perform joins, subqueries, and aggregations for deeper analysis
• Automate reporting and reconciliations
• Support variance, liquidity, and performance analysis

Each project demonstrates both the technical strength of MySQL (ETL pipelines, query efficiency, database design) and the business value it creates — enabling accurate reporting, stronger compliance, and data-driven decision-making.

I focus on writing SQL that is efficient, reliable, and finance-focused, ensuring organisations can trust their data and act on it with confidence.
