I'm going through this same thing this very month. I personally am responsible for architecting and building a complex data store, data pipelines, and interface. This is to be used for complex targeting based on rapidly changing data.
I am doing it by myself. I'm the architect and I'm the engineer. I'm drafting the design and building it. And I did it. By myself. Inside of a month.
At the same time, another team is working on the same thing. Dozens of people on the team. Architects and engineers and a couple of data scientists. They took three months to get their first design out and it failed during testing. Their estimate to next iteration is two more months.
My design passed all the tests but one in the first trial and I fixed the remaining bugs inside of a week.
There's a good chance that the other team is going to have their product pushed into production ahead of mine, which will negate the need for mine so my code will get pushed to some archive server and sit there gathering dust.
Same goes for the azure work that I'm doing. Again alone and without any support vs our internal IT apparatus who has infinite money and can spin up temp teams with the push of a button.
And 'round and 'round it goes.
