Turning complex data into clear decisions.
I help businesses understand what their data is really saying — and turn it into insights, visual stories and decisions that move the business forward.

The analyst behind the analysis
Rigorous data work.
Clear business language.
I connect rigorous analysis with the questions that matter to a business.
From analytical logic and data models to dashboards and executive narratives, I keep the work technically sound, visually clear and commercially relevant.
“Good analysis is not about showing more data. It is about making the right thing obvious.”

Data is only valuable
when it leads somewhere.
A dashboard, query or model is never the destination. The work starts with a business question and ends with a decision someone can explain and act on.
- 01
Understand
Start with the business question, not the dashboard.
- 02
Explore
Bring together the right data and find the signals that matter.
- 03
Explain
Translate analysis into clear insights and visual stories.
- 04
Decide
Make the result useful for the people who need to act on it.

Live data, made useful
Warsaw conditions.
One clear decision.
Twenty-four hours of public data, translated into a practical window for being outside.
Planning rule Window start between 06:00 and 19:00 (concluding by 22:00), selecting three consecutive hours with rain ≤35%, European AQI ≤60 and wind ≤30 km/h. Temperature is context, not a gate.
This is a transparent portfolio heuristic, not a scientific model.
