Hola! 👋

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

With +10 years of experience, I have an approach to software development significantly influenced by Extreme Programming practices (working in small batches, test-driven development, and continuous integration). I’m particularly interested in software design, biased towards easy-to-understand software solutions. I’ve combined long periods of working as full-stack engineer with periods leading software teams.
