Hello, I'm Serge. I'm a web and mobile application developer with almost 5 years of experience. My focus is Next.js, React Native, and SpringBoot (Java).
I’m passionate about making an impact through innovative development and look forward to the challenges that keep pushing me to grow as a developer and as a person.
When I’m not busy coding dynamic web applications or debugging complex systems, I’m someone who thrives on curiosity and creativity. As a full-stack developer, I enjoy solving problems and turning ideas into functional, user-friendly digital experiences.
Beyond the screen, I’m an avid reader (check out my currently reading section) and traveler who loves exploring new perspectives that inspire my approach to technology. I value continuous learning, whether it’s collaborating with a team or diving into the latest tech trends.
