You know what's wild? After 10+ years in this industry, I can architect a distributed microservices system in my sleep, but ask me to get Node versions, Docker containers, environment variables, and database connections working on a fresh machine? Suddenly I'm googling "why is my localhost refusing connection" for the 847th time. The actual coding is just the tip of the iceberg. Below the surface lurks the absolute monstrosity of dependency hell, conflicting Python versions, that one environment variable you forgot to set, Docker daemon not running, ports already in use, SSL certificates expired, and my personal favorite: "works on my machine" syndrome. Spent 30 minutes writing elegant code? Cool. Now spend 3 hours figuring out why your colleague's setup script doesn't work because they're on an M1 Mac and you're on Windows with WSL2 and nothing is compatible with anything anymore.
