I like certifications because the study process forces me to get breadth across a subject I might otherwise only scratch the surface of. That said, passing an exam and actually building something are very different things – the real value comes from putting the knowledge to work. Every cert here is backed by hands-on projects, prototypes, or production systems where I’ve applied what I learned.
