Hola 👋

I’m Sergio , a software engineer advocating for software development best practices and good software design.

With over 10 years of experience, my approach to software development is significantly influenced by Extreme Programming practices, such as working in small batches, test-driven development, and continuous integration. I’m particularly interested in software design, favoring easy-to-understand software solutions. I’ve combined long periods of working as a full-stack engineer with periods of leading software teams.
