How I work
- 01
A short call
Thirty minutes to understand what you have, what's not working and what a good result looks like. No charge.
- 02
A written proposal
Scope, timeline and cost on one or two pages, so you know exactly what you're agreeing to.
- 03
Build and hand over
Regular check-ins while I build, then documentation and a walkthrough so your team can run it without me.

Experience
About me
I'm Mateusz, an independent BI developer and data engineer based in Poland. I build Power BI reports, the pipelines that feed them and the automation around them, for teams that want their numbers in one place and trust them.
6+ years in BI. I started as an intern at Philip Morris International and worked my way up in-house, then moved to consulting and built reports for clients in different industries. Being on both sides taught me what makes a report people keep using: it answers their questions, it's fast, and someone on their team can maintain it.
