Models you can open and check.

This is where I started, and it's still half of what I do. If you need a model, a tool or research you can actually trust, this page is for you.

Financial modelling and valuation

DCF, comps, equity and credit analysis. Formula-driven end to end — no hard-coded values, no circular references, and every number traceable back to an assumption you can argue with.

Software and internal tools

Web, desktop, iOS. From the first spec call to the live version. Usually this is a spreadsheet that has outgrown itself and now needs to be something a team can actually use.

Research and analysis

Original data, gathered and checked by me, written for the person who has to make the call. Short, properly sourced, and clear about any gaps most people would lie to you about.

Everything is done the same way as the work you can see here. Clients stay confidential.

The ones I can show you.
