Summary:

I work full time as a Data Science Manager in Accenture Applied Intelligence US West. I became an Accenture employee after my previous employer, End-to-End Analytics, got acquired by Accenture in late 2020. My main job is to provide solutions that allow my clients to boost their income by optimizing everyday operations. Over the past two years, I have been mainly focused on forecasting and optimization for the automotive industry and promotion planning in food distribution.

I work 100% remotely and enjoy frequent visits to the office and clients in Europe and the USA.

Family:

Science September 2012 I'm happily married to Agnieszka. We have four great daughters: Clementine ( old), Matilda ( old), Jasmin ( old), and Aurora ( old).

We currently live in Poland, but we are open for relocation.

We love animals: especially dogs and parrots. For my whole live there was a dog sleeping in my bed.

If allowed by busy daily schedule I like to do DIY: building and repairing electronics and doing some woodworking.
