I worked with Izabela for a year, when she was assigned as a data analyst to our marketing team. Throughout this year, Iza worked on numerous marketing analysis including: seasonality decomposition, new channel impacts, ROI modelling, marketing channel value estimations, Brand impact on geo-split test and many more. Iza always stood out due to her ability to learn quickly, detail orientation and high work ethics. She always came across as hard working individual, who you could always depend on to deliver. Due to her work our marketing team was able to improve the blended conversion rate in German as well as decreasing our CPAs while maintaining a breakneck growth pace, which eventually led to the startup earning its Unicorn status.
I would happily recommend Izabela both as a very strong professional and also as a great person to work with.

Izabela is a proactive and committed worker. Her huge asset is her critical assessment of the status quo. She is a challenger. She is not afraid to a question things, but also comes up with solutions.
She is 100% reliable and very supportive.
She is a great team player and keeps colleagues together in and outside of work.
