About

I'm Samuel — most people online know me as Xynoos. A 17-year-old fullstack developer from Malang, East Java, currently studying Industrial Electronics at SMK PGRI 3 Malang.

I started coding because I wanted to build things that matter. That curiosity turned into Xynoos Vertex — where I build everything from the social media platform and cloud storage to the PCB design services and web development offerings.

I don't believe age defines capability. While my classmates study textbooks, I ship production code, design circuit boards, train AI models, and build IoT devices. Every product in Xynoos Vertex is something I've architected and built myself — not as a student project, but as real products for real users.
