Looking for my next growth role
Hi, I'm Andrzej! A growth professional with 7 years of experience. Looking to join a team built around ownership, data, and experimentation.

Experience overview
These are areas I've worked in directly — not just topics I know in theory.

Selected growth outcomes
A few of the clearest outcomes from a broader body of work.

Sendcloud

Working style
I don't wait for a defined playbook. I clarify the problem, take ownership and keep moving.
I like understanding why something works, not just applying the obvious tactic.
If I take something on, I make it work and care about the quality of the outcome.
I'm used to working with Product, Sales and CS to move shared initiatives forward.
