The last week I attended to the QCon London 2020 Conference (thanks mimacom for the opportunity!). It was a cool experience where I had the chance to learn from others' experience on software engineering. These are the notes I made for the talks that caught my attention the most:

ArchUnit is a great tool to enforce architectural rules for your java code base by writing simple unit tests.

Back in july I participated in JSCamp, a two day event focused on javascript-based technologies. Between all the awesome frontend stuff I saw there, there was one framework who really woke up the backend guy that lives inside of me.

What is a microservices architecture? The microservices architecture pattern consists in functionally decompose a project into a set of collaborative services. Each service will take care of a concrete functionality, a concrete domain. Services will be developed independently, avoiding coupling between them. If needed, services can communicate through an exposed API, using HTTP/REST calls, for instance. Using this approach, multiple developers can work on the same project in a more independent way. Each service will have its own database (schema or set of tables) which will not be accessed by…
