Hey,
I am a software engineer and I have been developing web for 3 years now. More than the framework or even the language I always drive my code to be clean and readable, performant and scalable. I have my preferences when talking about frameworks and I can argue about the pros and cons of each but I really believe that is possible to develop code with great quality with whatever language or framework.
I have focussed my work on the frontend for the last 2 years, working with angular (v1-v6) and react. Always working with unit tests, integration tests and e2e tests, I absolutely do agree in spend time testing code, looking forward to improving code quality. I write them with no purpose on coverage but yes, to be behavior driven.
Though my professional experience is being oriented to the front end, and JavaScript is my world, I can create things with any language or framework.
