Curiosity as a compass

My journey began with an endless curiosity for how things work — from computers and film cameras to ATM machines, always drawn to unravelling the underlying logic of technology. I thrive on creating robust solutions and tackling technical challenges, constantly seeking to learn new domains and master unfamiliar territory.

Originally from Greece, I embraced my love for real-world applications by co-founding a startup, an experience that fuelled my passion not just for technology but for the art of building businesses. To deepen my understanding, I pursued a master's degree in finance alongside computer engineering — an education that equipped me to bridge the worlds of technology and entrepreneurship with clarity and purpose.

Today, I call Amsterdam home and work at KPN, where I design agentic AI systems and cloud infrastructure for telecommunications — exploring the boundless possibilities that modern AI and cloud unlock for mission-critical operations. I devote my energy to tackling impactful, complex problems, collaborating and learning from others; each experience helping me uncover the influences and ambitions that define my journey.
