Data analysis & visualization.

Unlock the potential of your data and make better decisions - I turn a mess in spreadsheets into something you actually use.

Let us talk about your project

Who this is for.

Got data scattered across five spreadsheets, reports you assemble by hand every month, or numbers that tell you nothing? That is my thing.

I organize data, automate reports and build dashboards that actually say something - so you make decisions based on numbers, not gut feeling.

Scope

What you get.

A concrete scope - no hidden asterisks or surprises.

01

Reports and dashboards in Power BI

Interactive reports that show what really matters - updated automatically.

02

Analysis in Excel and Google Sheets

I organize, clean and analyze data so you can actually draw conclusions from it.

03

Spreadsheet automation

No more manual copying - spreadsheets that update themselves (Apps Script).

04

Data visualization

I turn tables into clear charts and stories you can see and understand at a glance.

What I build it with.

Power BI Excel Google Sheets Google Apps Script Python SQL

These are the tools I work with every day. If your data lives somewhere else - I am not afraid of new tools and get up to speed fast.

Pricing

What it costs.

I quote every project individually - tidying up one spreadsheet is a different story than a dashboard tying several sources together. My rate starts at PLN 130 net/h.

Hourly (Time & Material)

When the scope is not clear yet or the data may change. You pay for the time actually worked - flexibly.

Fixed price

When the project is well defined. You know the cost upfront, no surprises.

Not sure which fits? Write to me - I will advise after a short talk.

Process

How it works.

01

You show me your data

You tell me what you have and what you need to find out. The rest is on me.

02

We set the goal and quote

We define what the report should show and how long it will take. Straight up, no fluff.

03

I organize and build

I clean the data, build the analysis or dashboard, and show progress along the way.

04

Handover and support

I teach you how to use it and stay in touch in case something needs changing.

Work

See it in practice.

FAQ

Common questions.

My data is a mess - can you handle it?
Yes - that is often the starting point. I clean and organize the data first, then build the analysis or report on top of it.
What format do I get the report in?
Depends on the need - a Power BI dashboard, an Excel/Sheets file or visualizations. We agree on what works best for you.
Will the report update itself?
It can. I set up automatic refresh so you do not have to assemble anything by hand every month.
I am not a data person - will I manage?
Yes. I build it to be readable and show you how to use it. The technical side stays on me.

Got a project to talk about?

Just tell me what you need - it does not have to be technical, that is my job. I will get back to you and tell you straight whether and how I can help.
