About me

Hi! I'm Sergio Peris, known as Sertxu — a Full-Stack Developer and SysAdmin based in Xàtiva, Valencia (Spain). I currently lead IT operations as IT Manager at a local company, where I focus on reliability, performance, and building clean, maintainable systems.

I work with a range of technologies, including Laravel, Node.js, and C#, among others. Beyond my day-to-day work, I'm an open-source maintainer and content creator who enjoys turning complex ideas into knowledge worth sharing.
