Hi there! I’m Koray Kocaelli, a 25-year-old software developer with a passion for building scalable web applications and experimenting with new tech stacks. I thrive in collaborative environments where I can contribute across the full development lifecycle, from design to deployment. I’m currently seeking a full-time role where I can apply my Java/Spring Boot, Angular, React, .NET, and Flutter skills to real-world projects. I also love electronic music production and live performance, and I enjoy staying active with running and basketball. I’m curious about AI and blockchain, exploring them through self-learning. Having lived abroad through Erasmus+, I enjoy discovering new cultures and languages, and I’m currently learning German and Spanish.
