Ah, the classic "entry-level" job posting that requires mastery of the entire tech stack universe! The recruiter is essentially asking for a frontend dev (JavaScript/React/Redux), backend engineer (Node/Mongo), and DevOps specialist (Docker/Kubernetes/AWS) all rolled into one human being—at the price of one salary, of course. It's like walking into a restaurant and ordering a 5-star chef, server, and dishwasher combo meal for the price of a single hamburger. The tech industry's expectations have gotten so absurd that we're practically one job posting away from "must have invented time travel and colonized Mars by age 25."
