Turning Financial Data into Strategic Insights

👋 About Me

Hi, I’m Teslim Adeyanju

Chartered Accountant (ACA), Xero Advisor Certified, and Financial Data Analyst with more than a decade of experience at the crossroads of finance, accounting, and data science.

My career began with core accounting and finance—preparing management accounts, building forecasts, analysing variances, and ensuring compliance. Over time, I expanded into data analytics and machine learning, combining the rigour of accounting with the power of technology. This blend allows me not only to report the numbers but also to uncover the stories behind them and translate insights into strategy.

I currently serve as Treasurer on the Board of Trustees at Asylos, a UK-based charity that provides research to support asylum claims. In this role, I manage budgets, forecasts, and restricted funds, while also designing board-level dashboards that improve transparency and governance.

💡 In short: I turn numbers into meaningful stories that inform strategy and drive results.
