A usually-remote mate had coming to the party. We had in charge to keep building a hotel management system together. A thing that I was dreamed of. Sharing codes! The project was started on — if I'm not mistaken — 2015. A complex building inapropiately designed had feeded us with full of stinky dressing spaghetti. Thus, we had reached maximum level of laziness carried for next couple of months. No, not month. Year!
People mostly learn by mistakes. That's why that time I've keep reading on how system should properly be designed. And have to keep loving this kind of work.
Also, since then, one of my dream project I want to create is ERP. And that's why I (re)try to learn this domain from last month (Jul 2019). All by my self.
