A digital architect is like someone who plans how to build a really cool house, but instead of a normal house, they plan how to build a really cool computer system.
Just like how you need a plan and blueprint to build a house, a digital architect needs to have a plan and design for the computer system they want to build. They use different tools and computer programs to create a virtual model of what the system will look and work like.
Once they have the plan and design, they work with other people called software engineers and programmers who help them actually build the computer system.
The digital architect is like the boss of the project who makes sure everything is going according to plan and that the system meets all the requirements that were set at the beginning.
So basically, a digital architect is someone who designs and plans a really cool computer system and makes sure it gets built the way it should be.
