## Headline

Data Analyst \| SQL • Python • Power BI • PostgreSQL • Advanced Excel • Generative AI\. Business Intelligence, Data Visualization, and Reporting Solutions for Data\-Driven Decision Support

## About

I specialise in converting large, complex datasets into structured insights that senior stakeholders use to make faster, more confident decisions\. With hands\-on experience across HR, finance, and supply chain functions, I design and deliver end\-to\-end analytics solutions — from raw data extraction to boardroom\-ready reporting\. Core technical competencies: • Power BI dashboard development using DAX and Power Query, reducing manual reporting cycles by 40%\+ • SQL and PostgreSQL query optimisation to surface trends across multi\-table relational databases • Python\-based ETL pipeline development and exploratory data analysis on structured and unstructured datasets • KPI framework design that maps operational metrics to measurable business outcomes Across multiple business units, my work has contributed to a measurable improvement in reporting accuracy, enabled real\-time operational monitoring, and supported cross\-functional performance analysis for teams of 50–500\+ employees\. I work best at the intersection of data engineering and business strategy — translating technical output into clear, decision\-ready narratives for finance directors, HR leads, and operations managers\. Open to full\-time and contract opportunities in data analytics, business intelligence, and reporting roles\.
