What I've learned while leading the backend architecture of a university software project

I'm a 20-year-old computer science student leading the development of a software project called Skyline Computer World. Rather than rushing into features, I decided to start with the architecture: designing the database, setting up NestJS, PostgreSQL, Prisma, and establishing a modular backend structure. The process has involved plenty of debugging, redesigning, and learning—from Prisma migrations to project organization—but it's reinforced how important a solid foundation is for long-term maintainability. I'd be interested to hear from more experienced backend engineers: What architectural decision had the biggest long-term impact on one of your projects? If you were starting a backend from scratch today, what would you do differently? submitted by /u/amjakez [link] [留言]
