Financial Data Analyst | Chartered Accountant | Turning Financial Data into Strategic Insights

Visitor Badge Github LinkedIn Badge StackOverflow Badge Email Badge

πŸ” About Me

I’m a Financial Data Analyst and Chartered Accountant with over a decade of experience helping organisations make sense of their financial data and turn it into strategic action. My work sits at the crossroads of finance, accounting, and data science, where I bring numbers to life and uncover insights that drive better business decisions.

I specialise in using tools like SQL, Python, R, Machine Learning, Power BI, and Advanced Excel to analyse performance, streamline reporting, and build forward-looking models that support forecasting, risk assessment, and investment planning. From working with UK-based firms to international organisations, I’ve helped teams modernise traditional finance functions, reduce manual workload, and deliver insights that improve both financial control and commercial impact.

I combine deep financial knowledge with technical skills to build systems that are not only accurate and compliant with UK GAAP and IFRS, but also intelligent, adaptable, and aligned with business goals.

πŸ’‘ My Mission

To bridge the gap between traditional finance and modern data scienceβ€”creating smarter, faster, and more efficient financial ecosystems that empower confident decision-making.
