How Systems Analysis coursework transformed my approach to problem-solving.

---

My university course in Systems Analysis and Design changed how I see software. It's not just about code; it's about understanding the whole system.

## Thinking in Systems

Before writing any code, I now ask: What are the inputs? What are the outputs? Who are the stakeholders? What are the constraints? This simple framework prevents countless hours of rework.

## UML Still Matters

Yes, we have modern tools, but sketching a quick sequence diagram before implementing a complex feature saves debugging time. Visual thinking clarifies logic that words obscure.

> Systems thinking is a superpower. It applies everywhere, from database design to startup strategy.

## Feedback Loops

Every system has them. In AUXILIARE, user engagement drives algorithm recommendations, which drive more engagement. Understanding these loops helps design for growth, not just functionality.

You can walk through the interfaces it produced in [the Auxiliare demo tour](https://auxiliare.vercel.app), the front end only, without a live backend.
