Hi! I’m a freelance web developer from France. After a career in the audio industry, I moved to the web because of how fast it allowed me to build, iterate, and ship great user experiences. React has been a major part of this success story. I’ve also been building and maintaining open-source software since 2007, from bare metal to the cloud, with libraries for React, Next.js, Fastify & Prisma. I love the open sharing of code we find useful, and the community it creates around it.

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.
