How do you design systems that are scalable and maintainable?

I start by understanding the business growth projections and expected user load.

Architecturally, I favor modularity—breaking the system into well-defined services or

components. For example, using microservices in .NET Core allows independent scaling.

On the frontend, reusable React components improve maintainability.

I also enforce clear API contracts and automate testing to ensure future changes don’t

break things. Documentation and knowledge sharing are key so the system is maintainable

even as teams grow or shift.
