Georgios Diamantopoulos is a pragmatic engineer with a unique ability to synthesize complex information and translate it into actionable systems. As co-founder of Zero to MVP since 2019, Georgios and his team have built 25+ scalable systems by taking a holistic view of requirements, constraints, and sustainability. In parallel, his personal journey through the physical challenges of our industry led him to dive deep into health research - not as an outsider, but as someone living the same reality as every developer: the gradual physical toll of prolonged sitting, the cascade of adaptations our bodies make, and the realization that conventional wisdom about developer wellness misses the mark. This first-person perspective, combined with systematic thinking, allows him to bridge cutting-edge research with the day-to-day reality of tech work, addressing the challenges we all face but rarely discuss openly.

I’m a software engineer working at Dynatrace and Pebblebyte, where I focus on frontend, DevOps, and making sure observability is everywhere. When I’m not deep in code, you’ll probably find me kitesurfing, road biking, swimming, or hanging off a rock wall. Whether I’m debugging or chasing wind, I’m always looking for that perfect flow.

With a passion for creating seamless cross-platform experiences, my journey in tech started not with programming, but as a consultant in the tech industry. The desire to build and innovate led to a shift in focus towards software development, particularly mobile app development, where the thrill of solving complex problems and crafting user-friendly applications became a calling. Co-founding Frontend Queens was a natural extension of this journey, inspired by a commitment to inclusivity in tech. This community was born from the belief that everyone, especially women, should have the opportunity to thrive in technology. By fostering a supportive environment, we aim to empower women to break barriers and pursue fulfilling careers in this ever-evolving field.
