About

I’m a Full Stack Developer with expertise in Java, Spring Boot, React, Node.js, and scalable system design. Over the past few years, I’ve been building robust, end-to-end solutions that improve efficiency and solve real-world problems. At Namekart, I’ve led the development of domain management dashboards, real-time location tracking systems, and large-scale data scraping tools. Previously, at Rydeu Logistics, I focused on backend development — optimizing APIs, enhancing system security with Keycloak, and building global banking modules. I enjoy exploring new technologies, solving complex challenges, and creating reliable, impactful products.
