Slevomat.cz is the largest daily deal/bulk discount website in the Czech Republic. Slevomat.cz is one of the most successful startups in Czech and I had been there since the beginning (2010-2016).

I was responsible for design, product development and marketing (mainly inbound). My goal was to increase ecommerce rate and gain more relevant visitors. I had managed AB tests to validate my product design decisions.
