Who I Am

I’m Eratosthenis Kostaras — a digital marketing strategist with deep experience in performance marketing, analytics, and MarTech integration. My work lives at the intersection of data, tools, and decision-making. I enjoy solving hard problems, asking the right questions, and designing systems that quietly perform.

I believe that good marketing is both structured and experimental. It listens before it speaks. And it respects both the numbers and the people behind them.

How I Work

I approach marketing as a system — one that’s measurable, flexible, and aligned with business context. I focus on what works, but I’m more interested in why it works. Whether it’s optimizing campaigns, refining tracking architecture, or exploring user behavior patterns, I aim for clarity, consistency, and insight.

Over time, I’ve come to value frameworks over hacks, signal over noise, and strategy over trends.

What I Value

  • Clarity over noise
  • Curiosity over certainty
  • Iteration over perfection

Beyond Work

I live in Greece with my family. I spend a lot of time walking, reading, and thinking about how things fit together — from marketing funnels to story structures.
