They don't mention time requirements. While I have independently done all those things mentioned, nobody can do them all at average joe 40 hour a week level combined without having absurd burnout quickly or dying from sleep deprivation.
And even then, you aren't working at average levels, you would be far below it due to overexertion.
You can't have one guy write the website, maintain the servers, support the office IT, act as tech support, and manage all the site databases. Not on something as big as PA, at least. Maybe on a site with 100k views a month, where the server is just an ECS2 instance and your office firewall is a dlink router with iptables.
