💡 Bridging Dev & Marketing.
I am looking for challenging roles where my technical and management skills can make a real impact. Considering any vacancies, from developer/integrator to CTO or team lead, or for example, an astronaut ;) If you have an ambitious idea, like a mission to Mars or so, don't hesitate to reach out !)

P.S. AI opens up entirely new levels of automation in advertising: from linking payment cards to A/B testing. I would like to try to create an autonomous system that would require minimal human intervention in advertising processes: from trend analysis to automated creative generation and bid management.
