ZS LT HORVÁTH

Passionate about computers since childhood, I turned my curiosity for coding into a career in backend development. I’ve built and improved everything from legacy monoliths to new services, focusing on robust, scalable solutions for high-traffic environments. I thrive in collaborative teams, enjoy sharing knowledge, and I am always eager to learn and make a real impact.
