What our team members say
Every pixel has a purpose. Every message has meaning
Every visual I create, whether it’s a landing page, ad banner, or campaign asset, is designed to convert. At MediaHorn, design is about performance as much as aesthetics, and that balance keeps my work sharp and focused. I collaborate closely with the media buyers and strategy teams, which helps me stay aligned with what really works. I’m trusted to experiment and improve my work independently, which makes every project more meaningful. Seeing the real-time impact of my designs is incredibly rewarding. It’s a creative role with real business value, and that’s rare to find.
Emails should feel personal, not promotional. That’s the art I bring to our campaigns
I manage our promotional and upsell email campaigns, making sure every message delivers value and drives results. At MediaHorn, we don’t just send emails, we build smart, data-driven flows that convert. I love how much room I have to test, learn, and scale ideas without getting stuck in unnecessary processes. The feedback loop is fast and the impact is visible, which keeps things exciting. I’ve grown my technical and strategic skills here more than I expected. Being part of a team that moves quickly and supports your growth makes all the difference.
