About

I explain data tools like a person, not a press release.

For twelve years I have built dashboards, broken them, migrated between every major platform and learned which promises hold up. just-tim is where I share the honest version, the bit the vendors leave out.

The story so far

It started as a side channel explaining Tableau the way I wished someone had explained it to me. Twelve years on, that has grown into more than six hundred videos, articles and guides, and a community of people who do the actual work. I left the “Tableau Tim” name behind because the tools kept changing and the curiosity did not. The point was never one platform. It was always making the complicated stuff make sense.

How I approach it

The house style
01

Tool-agnostic, on purpose

I have no horse in the race. If a tool is the right one for the job I will say so, and if it is not, I will say that too.

02

Show the actual work

Real datasets, real edge cases, real mistakes. No toy examples that fall apart the moment you try them on your own data.

03

Opinions, clearly labelled

A hot take is fine as long as you know it is one. I separate what the tool does from what I think about it.

What I cover

The whole pipeline, end to end.

Platforms & BI tools

Tableau, Power BI, Hex, Looker and the new AI-native challengers.

Video

Modelling & SQL

The unglamorous layer that decides whether the dashboard is any good.
