    About Me

    A visionary growth strategist and intrapreneur with a passion for transforming ideas into impact. With over 15 years of experience across ICT, Life Sciences, and dynamic start-up ecosystems, I thrive at the crossroads of business strategy, digital marketing, and customer experience.

    Data-driven yet deeply creative, I specialize in crafting and executing go-to-market strategies, optimizing funnels, and driving brand growth in both B2B and B2C landscapes. My expertise spans business development, inbound marketing, growth hacking, and conversion optimization—always guided by a “test, learn, and evolve” mindset.

    Currently shaping the future of workplace excellence at Great Place to Work® Hellas, I collaborate with leadership on strategic growth, digital innovation, and competitive research. My journey includes working with global organizations and high-growth ventures, earning recognition through elite leadership programs designed to cultivate exponential thinking and impact-driven leadership.

    I believe in continuous learning, fearless experimentation, and creating workplaces and brands that inspire. Let’s connect and build something remarkable together! 🚀
