Sales and revenue dashboard built in Power BI

A real dashboard, built on a public dataset.

What changes

Stop rebuilding the same report every month.

Today

Three days of copy and paste.

Figures pulled from several places, pasted into a template and checked twice. By the time anyone reads it, the numbers have moved on.

After

One screen, refreshed on its own.

The same numbers, cleaned once and connected properly, answering the questions your team actually asks.

What I do

Four things, done properly.

Reports that build themselves

The monthly report that takes you three days, running in minutes instead.

Data you can trust

Getting your data ready for the decisions that matter. Cleaning, transforming and consolidating information from scattered sources.

Excel · Power Query · SQL

Every change documented

You get a full cleaning report alongside your data: what I found, what I corrected, what I flagged for your decision. If I don't know something, I ask. I never delete without your approval.

Included as standard

See one for yourself

A full cleaning report, start to finish: every issue found, every correction made, everything flagged back for the client to decide, and the validation rules that stop the same mess returning next month.

What the numbers turned out to be saying.

23^%of kilometres earning nothing

Is your fleet costing more than it earns?

A logistics fleet covering a million kilometres a year, with 23% of them earning nothing. The fix was route planning, not more vehicles.

Construction finance dashboard built in Power BI

The method transfers to any industry. If your data doesn't look like the examples above, tell me about it.

How it works

Five steps, and you see it early.

We talk.

Not about tools. About what decision you're trying to make, and which question keeps coming back without a good answer.

I look at your data.

Whatever state it's in. I'll tell you what's there, what's missing, and whether it can answer the question you asked.

I clean it, and I write down what I did.

Every correction, every oddity flagged back to you. Nothing is deleted without your say-so.

You see a draft early.

Before it's finished, while it's still easy to change. Most of the good decisions happen here.

You get the finished thing, and you know how it works.

The dashboard, the cleaning report, and a walk through how to refresh it yourself.

Before you write

Questions people ask.

Does my data need to be tidy before I send it?

No. That's my job. Messy is normal, and the mess usually tells me something useful.

Do I need to buy Power BI licences?

Not necessarily. I can build in Power BI Desktop, which is free, and hand you the file. Anyone with Desktop installed on Windows can open it. You'd only need paid licences for a dashboard in a browser, on phones, refreshing on its own, or shared round a team. I'll tell you which you need before we start, not after.

How long does it take?

Usually one to two weeks from the point your data reaches me, depending on how many sources and how many pages. I'll give you a date before we start.

What do I actually get at the end?

The dashboard itself, the cleaning report showing every change I made, and a short walkthrough so your team can use it without me.

Where are you based?

It doesn't matter, and that's the point. I work in Polish and English, remotely. A Polish business in Chicago gets exactly the same as one down the road.
