Through the use of the API Services (e.g., developed in .NET Core or Laravel) with high quality SPA front-ends (e.g., developed in VueJS and CapacitorJS/Cordova for mobile apps) as an architectural pattern, we can create very complex web solutions.

Can't say enough about the combination of .NET Core and VueJS.  Both are easy to learn, delightful to work with, versatile, adoptable, and opens doors to opportunity.
