I'm a full-stack web developer. My preferred stack is currently Ember.js and Laravel (PHP) with a pinch of Node.js. I enjoy working with GitLab, which is an amazing development platform in my opinion. It's not only providing source control but also including one of the bests CI/CD tools available.
Reinventing the wheel and bikeshedding are one of the main blockers for a high productivity. Developers time is too precious to be waste on problems that already have been solved by others. Therefore I encourage existing standards like JSON:API specification.
The combination of test-driven development, conventions over configuration and DevOps unlocks an amazing productivity while ensuring good code quality at the same time. It's a key factor to success - not only but especially for enterprise applications.
