I'm Dion, a Master's student in International Design Business Management at Aalto University with proven marketing results. In 2023, I doubled Hetijetti's revenue from €7,500 to €15,000 through data-driven social media campaigns. Testing ad performance, optimizing based on results, and creating all marketing materials and copy. I went all in on what worked (short-form video, SEO optimization, strategic promotions) and cut what didn't. What makes me stand out: I combine creative execution with analytical thinking. I understand what resonates with audiences because I've tested it, measured it, and iterated on it. I also won the ElevenLabs Tech Challenge at Junction 2025 by leading UX design for an AI-powered game, which taught me how to design experiences people genuinely enjoy. I've worked five years at Kesko while studying, consistently going beyond expectations and juggling work across two cities, so I know how to work hard and deliver under pressure. I'm bilingual (Finnish/English), thrive in multicultural environments, and I'm ready to create campaigns that balance creativity with measurable business impact.…I'm Dion, a Master's student in International Design Business Management at Aalto University with proven marketing results.
