About

Currently working on growing Optibase - an A/B testing and experimentation platform for teams that want to stop guessing and start making decisions based on real user behavior. Outside of that, I work across marketing, digital media and online projects - mainly focues on: • building and growing social media pages • experimenting with content and distribution • improving landing pages and funnels • learning what actually drives clicks, conversions and attention
