About me

My name is Josué Sandino, but in the technology community many people know me as jsandinoDev. I'm a full-stack developer and Site Reliability Engineer with expertise in TypeScript, C#, and infrastructure. My computer science journey started at the age of 12, with unsuccessful attempts to download games, and since then, my passion for software development and systems engineering has only grown.

I specialize in designing and managing complex distributed systems, Kubernetes orchestration, and cloud infrastructure. With deep Linux knowledge and hands-on experience with storage systems like NetApp and Ceph, I focus on building resilient, scalable solutions. I'm also expanding my expertise in web3 technologies and AI development, creating projects that bridge infrastructure and innovation.

When I'm not architecting systems or writing code, you'll find me lifting weights, playing video games, or exploring emerging technologies. I have a deep passion for music— I play guitar, saxophone, piano, and ukulele. Classic and minimal techno fuel my focus sessions. Open source is my playground, and I'm always building innovative, impactful solutions. ♭
