About Me

I am a Financial Data Analyst, ACA Chartered Accountant, and Microsoft Certified: Power BI Data Analyst Associate (PL-300) and Azure Data Fundamentals (DP-900) professional, with over a decade of experience in financial reporting, FP&A and data analytics.

I help organisations turn complex financial data into trusted, decision-ready insight. I combine finance and accounting expertise with Power BI, Microsoft Fabric, Azure data services, SQL and Python to improve reporting quality, automate repeatable processes and strengthen financial controls.

I build Power BI semantic models, star-schema data models, SQL data pipelines and Python-enabled financial workflows. My focus is reliable, scalable and auditable reporting—helping finance teams move beyond spreadsheet-led processes towards governed self-service analytics.

💡 Approach: Finance expertise first; data and automation as the enablers. Clean data, controlled processes and transparent logic make better financial decisions possible.

FDA Toolkit — Enterprise Financial Data Toolkit

PyPI versionPython versionsLicenseDownloads

I am the creator and maintainer of FDA Toolkit, an open source Python project I architected and developed to solve real world challenges in financial data analysis.

The toolkit enables financial analysts, accountants, and data professionals to produce reliable, auditable, and repeatable analytics by replacing fragile spreadsheet driven processes with structured validation, transformation, and reporting pipelines designed for production use.

Financial analytics capabilities

  • Clean, standardise and validate financial datasets before reporting or analysis
  • Support reconciliations, data-quality checks and traceable financial workflows
  • Automate repeatable finance and FP&A analysis tasks using reusable Python functions
  • Apply audit logging and consistent error handling to strengthen operational control
  • Provide one-line utility workflows, including ftk.quick_clean_finance()
  • Support integration with SQL, Power BI and broader financial-data pipelines

Install:

pip install fda-toolkit
