## About

I architect human-centered software systems at the edge of research and innovation. From HCI theory to prototyping emerging tech, I turn experimental ideas into practical interfaces.

I discovered interaction through an optical stylus at age 4, wrote my first lines of code by 6, and programmed automates at
\8. Decades later, the passion still burns—coding and interface experiments never left my side.

I hold a double master’s in network & cybersecurity and web & interaction, with a PhD in Human-Computer Interaction. Now a fullstack engineer, I design interactive systems where cutting-edge tech meets human context.

I’m a strong believer in libre and open-source, and I contribute whenever I get the chance.

🌱 What Drives Me I’m passionate about how people and technology shape each other. I prototype ideas into real tools, exploring how research can transform into intuitive, impactful systems. I build interfaces that invite curiosity—not just use—combining rigor with exploration. For me, interaction is a playground, and experimentation never stops.

🌐 Domains I've Explored ➜ Human–Computer Interaction (HCI) and interface architecture ➜ Fullstack development (web, embedded, cloud-native) ➜ SaaS platforms and scientific tooling ➜ Data visualisation and interactive modeling ➜ Educational & research software ➜ Cybersecurity and distributed systems ➜ Semiconductor interfaces & tooling ➜ Open-source projects ➜ ... and many more
