How do you make architectural decisions in a full-stack project?

I start by aligning with business goals—whether it's scalability, speed to market, or

maintainability. Then, I evaluate the tech stack, team skillsets, and existing

infrastructure. For example, in one project, I chose a microservices-based backend using

.NET Core with a React frontend. We used API gateways to separate concerns and ensure

scalability. I involve senior devs in early discussions, create a proof of concept if needed,

and always document the rationale for future reference.
