About Me
I started my career as an electrical engineer, but quickly realized my true passion was in software. In 2019, I taught myself to code — starting with JavaScript and React — and haven't stopped since. I enjoy building clean, intuitive applications and continuously expanding my skill set. When I'm not coding, you'll find me exploring new technologies or working on side projects that challenge me to grow.
