I'm an agency lead and digital media expert who loves combining thinking with doing to solve complex business challenges.
See what I doI started as a PPC expert at Mito Group, leading a small team of 3. Early on, we realized the best work happens when we combine systems with client understanding. So, we started builing automated reporting, campaign frameworks, and testing protocols that let us scale efficiently.
That foundation led to a breakthrough in 2017: our team won Nokia's global media tender. We went from managing local campaigns to coordinating 300+ projects annually across 150 countries with €5M in ad spend.
Over five years, I scaled the team from 3 to 17 experts. But the real growth was in capability — putting Mito on the map in the global agency space and establishing relationships with regional and international brands across multiple markets.
For Nokia, we managed 300+ projects annually across 150 countries. We orchestrated a global rebranding campaign with synchronized activations in 50 cities, including a digital takeover of Times Square.

View PresentationMarketing at scale is an engineering problem—structured processes and data architecture. But it's also human. You need empathy to translate systems into clear strategies.
Teams beat individuals. The work I'm most proud of is what I enabled other people to accomplish through better systems.
