I don’t feel attacked, sounds pretty good actually:

Imagine we’re building a giant LEGO castle with lots of rooms, towers, and secret passages. An IT infrastructure architect is like the person who plans how all the LEGO pieces fit together to make sure the castle is strong, safe, and has everything it needs, like doors that open and close and lights that turn on! They design how all the computers, networks, and other techy things work together so everyone can use them easily and safely. They also check to see what the computer system needs and find solutions for any problems that might happen.
