I can train a model. Why does the rest overwhelm me?

You can train a model. You can tune it, improve it, make it perform in a notebook. But ask you to serve it, watch it, retrain it, keep it breathing in production, and you freeze. That is not weakness. That is an honest reaction to being asked for a skill you were never taught. Here is what nobody told you: machine learning engineering and machine learning systems are different professions wearing the same job title. One builds the mind. The other builds the body that carries the mind through the world — the data flowing in, the logs, the alerts, the rollback when it breaks at 3 a.m. You trained for the first. You are being asked to invent the second alone, without even a map of what it contains. You cannot think your way out of overwhelm. You can only act your way out, one piece at a time. That is the only move that was ever available to you. Take it today, not once you feel ready.
