About Me
Who am I?
Hey, I'm Devan Ferrel, a final-year Information Technology student at Universitas Brawijaya with 2 years of hands-on experience in backend and DevOps engineering.
I specialize in building scalable systems with Golang, .NET, and Laravel, backed by solid DevOps practices using Docker, Kubernetes, Ansible, and AWS. I also work across frontend stacks like Next.js and Tanstack Start.
Outside of work, I enjoy solving competitive programming problems, playing chess, and discovering new music. Fun fact, my favorite band is Wave to Earth.
