I have been a backend developer for eighteen years without writing a single line of code on the client-side, but with the dawn of single-page applications, my cooperation with web developers got closer. I started to observe their work with interest. There are so many exciting possibilities on the frontend side. It made me consider to build up my technology stack and become a full stack developer.
I noticed that web developers create TypeScript models and services that reflect our backend model and REST services. It was a tedious job. What is more, after they finally mirrored what we had on the backend, it wasn't the end. Because we always have to keep in mind one thing that is very common in software development... CHANGE. Due to some new business requirements, backend services were modified. The change forced frontend developers to reanalyze backend services and refactor frontend applications so that they would match the server-side.
