Laura is a software engineer obsessed with front-end development. She is also teaching teenagers about Web Technologies. 2 years ago Laura was on the Dark side - developing with COBOL programming language on Mainframe supercomputers! Due to slow evolvement and limitations of used technologies, she decided to shift them pretty drastically. Laura believes we shouldn't stick to any specific technology in this rapidly evolving IT World, but try and use various different ones instead. Every new experience increases our creativity, knowledge, curiosity and expands mindset. Her latest discovery was music programming, and she wants to share it with us!

Georgios Diamantopoulos
Zero to MVP, Greece
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.
