I'm a full-stack software engineer with 5 years of programming experience, currently working at EXTRA.DEV. I have experience in software architecture and AI/ML engineering. When I'm not coding, I like to discover new music and go to the gym. You can even see what I'm currently listening to on Spotify below.
