Hello! I'm Felix, a self-taught programmer from Jakarta, Indonesia. I'm experienced in web development, particularly React and TypeScript, and also highly comfortable with managing Linux systems, building CI/CD pipelines, task automation, and managing deployments.

I have a knack for automating as many things as possible, and I'm always looking for new ways to make things more efficient.
