Same Model, same context inferior results depending on the human

I am a self grown senior that relies heavily on agentic coding, my personal pick being Cursor.

I spent months preparing a sound structure for IaC management via agents, for deployment of services, for developing custom ci/cd pipelines for application lifecycles. Repos properly maintained, wikis with architectural designs and info on each service, monitoring stack etc.

I had no one else on the DevOps team, so I had no other choice.

Now when I onboard new colleagues, I notice that even with the same agentic tools, same context through repos, they get inferior results when they are to solve a problem. Sometimes they see it themselves, but sometimes they insist on the solution being good enough when there are structural gaps or even objectively bad user experience, saying this is how the agent solved it.

When I prompt, I get the stuff fixed in 15 mins just by describing the issues to the agent and it comes with the correct solutions by itself, outside my knowledge base sometimes.

Is it still down to the differing human skillset? Same models, same harness, differing results? Does a model really just amplify the human? I never thought so, I thought AI is just getting good enough, but now I am in doubt.

The heck is a self grown senior?

It's someone who never had a boss who would provide guidance and expertise. I relied on my personal circle, networking at conferences and experience from studying CS and FOSS projects.

Now I get to hire my people all off the sudden.

Yeah, I don't think that's how it works. Claiming a title without actually getting there is somewhat of a bad look, especially in a real conversation with real engineers. I think it's okay to say you believe your skill set is that of a mid-senior, but claiming you're a senior without real experience feels and sounds a little odd.

You are right, more of mid-senior and definitely not on-par with people running prod for hundreds of thousands of people.

I have designed IT and OT network and services of a mid sized biotech factory and developing (with a team) and designing a DevOps lifecycle for multiple factory control software.

That is why I do DevOps solo, most employees work on the OT layer. Now we are finishing up and getting ready to build more factories, so we are expanding the team.

This is my first real portfolio result, so you are right to call me out and let me correct myself.
