Infrastructure
On-premises systems, hybrid environments and public cloud. A foundation to build on.
DATA ENGINEER / POLAND
Piotr
Mrówczyński.
Data platforms.
From infrastructure to impact.
I bring together software engineering, cloud infrastructure and data. I build systems that help people work, understand and make decisions.
EXPERIENCE
- CERN
- ownCloud
- comparis.ch
- Adevinta
- Colliers
I look at the whole system.
From where data comes from to the people and problems it serves.
Data platforms
Pipelines, models and data quality. From the first source to a platform I take responsibility for.
Application
Analytics, data products and integrations. Technology earns its place by solving a real problem.
Why polskachmura.pl?
Polska.
Chmura.
Polska — because I’m from Poland.
Chmura — because my professional life revolves around the cloud.
From on-premises infrastructure, through hybrid environments, to public cloud. This domain brings together where I come from and what I work on every day. “Chmura” is Polish for “cloud.”
My personal corner of the web. About data, technology and the things I build.
From practice.
From curiosity.
I write about what I’ve tried. I build to understand.
