allegro ads - ads platform for the biggest polish marketplace

When I started work in Internet Industry, long time ago, I always dreamt about job in the biggest and most famous polish marketplace called Allegro. Allegro is still a legendary brand and precursor of polish internet industry at all. Its good to have a dreams even big ones ... cause there is always possibility that your dream became truth... My Allegro's Challenge was to design brand new platform for "making in-market customised ads" (similar idea to AdWords). I worked with 3 scrum teams on different fileds (frontend, statistics, backend, data mining). Our product is one of biggest source of income for Allegro after marketplace... and Warsaw Office Rockssss... The best office ever I've worked in my life :)
