Freelance Power BI consultant: dashboards built for your business

I build dashboards that show your key numbers in one place: with filters, comparison to plan and a clear definition of every metric. As an independent Power BI consultant, I take the project from the data model to handover.

When I can help

  • You check results in several files and systems before you have the full picture.
  • Management gets a different report layout every month, so periods are hard to compare.
  • You need one KPI view with filters for region, product or sales rep.
  • Your current Power BI report is slow, hard to read or shows different numbers than Excel.

What you gain

  • Your key numbers at hand, on your phone too.
  • One definition for every metric — no more arguments about which number is right.
  • Comparison with plan and the previous period without manual calculations.
  • The report refreshes automatically or with one click, depending on the sources.

What I do

  1. We agree who will use the report and which questions it has to answer.
  2. I design the data model: fact and dimension tables, relationships, a calendar.
  3. I write DAX measures: margin, year-on-year growth, plan vs actual, shares.
  4. I design clear report pages — overview first, then details, then data quality.
  5. I set up refresh and sharing within the agreed scope.
  6. I check that the dashboard numbers match your existing reports.

How I approach it

A good dashboard starts with questions, not charts. Before I build the first page, we write down 5⁠–⁠10 questions the report has to answer and the definitions of the metrics. That way you don’t end up with another report that looks nice but nobody uses. If your company doesn’t have Power BI Pro licences, I’ll show you what can be done in the free Power BI Desktop or in Excel — that decides how the report is shared.

EXAMPLES

An example on fictional data

Client data is confidential, so I show the same kind of work on fictional data. The results are calculated from that data — these are not client projects.

Independent report views, each on its own fictional dataset — values are not comparable between views.

Sales and margin dashboard

Problem
Sales, margin and plan figures sit in several spreadsheets — there’s no single view for management.
Data
12 months of sales in two channels, 10 product categories, plan and actual for 5 regions.
Work
A data model with a calendar, DAX measures (margin, growth, plan vs actual) and three report pages: overview, profitability, regions.
Result
One report that answers: how are sales going, which categories drive margin and which regions are on plan.
Tools
Power BI, DAX, Excel

What I need for a quote

  • A list of questions and metrics the report should cover
  • Data sources (files, ERP or CRM, a database) and their approximate size
  • Who will use the report and how they should receive it
  • How often the data needs to refresh

Questions

Is a paid Power BI licence required?

The free Power BI Desktop is enough to build the report. Sharing reports with other people in the Power BI service usually requires paid licences, so we agree the sharing method at the start.

Can the dashboard be built in Excel instead?

Yes. For small teams and simpler data an Excel dashboard is often the better choice: no licences and no training needed. I’ll recommend what fits your situation.

Do you work with companies outside Poland?

Yes. Reports and documentation can be in English and the work is fully remote. Invoices are issued through Useme, a Polish freelance platform that holds your payment until you accept the work — in EUR if you prefer.

What happens after the 30 days of support?

After the 30 days I quote small fixes separately, always before starting, or we agree ongoing support. The documentation also lets someone else take the solution over.

How do we work together, and how does billing work?

You describe the problem in a few sentences. Within 1 business day I reply with questions or a proposal, then send a free quote with the scope, timeline and price. I bill through Useme, a Polish freelance platform: you get a VAT invoice, and your payment can be held by Useme until you accept the work. An NDA is available on request.
