“Experience does not matter much in the software world”? Please tell me you’re joking. Writing in a modern language doesn’t prevent someone from writing crap code. After 22 years of working with engineers of all ages across huge companies and startups, I’ve found that experienced engineers write better, tighter, and more efficient code in any language. As with any profession, experience does indeed matter. A lot. Expertise comes with practice. Lots and lots of practice.
