Tutorials

I have created a range of free video tutorials and Excel templates that can help you grasp the basics of using Excel and Financial Modelling. My tutorials can also help you use a variety of formulas to automate repetitive processes.

Maximise the Value of Your Business Data

I can help you take full advantage of your business data. I can take care of data analytics and financial modelling for you, or teach you how to effectively analyse data for yourself so that you can extract actionable insights from any dataset.

Your business data — when effectively analysed and visualised — can help you to better understand your business’s performance, make informed business decisions, impress investors and raise capital.

Use and Create Spreadsheets with Confidence

If you’re a complete beginner when it comes to spreadsheets, I’ve designed online tutorials and courses to help you develop the skills you need to use, create and understand spreadsheets with confidence.

You can develop your confidence using Excel or Google Sheets with hands-on learning — my courses give you the chance to apply lessons to practical examples.

Save Time and Money

My Excel and Python expertise means I can carry out in-depth data analysis and extract valuable insights as quickly as possible. These insights can then be used to streamline business processes, improve business performance and reduce unnecessary costs.

Or if you’d rather take a DIY approach to your spreadsheets and data analysis, my courses and tutorials can help you learn how to do so quickly and effectively.
