Robby has a chat with Carlos Blé, the CEO of Lean Mind, an organization focused on boosting the growth of developers and teams. Carlos is a software crafter, entrepreneur, mentor, speaker, podcaster, blogger, and author of several tech books in Spanish (Diseño Ágil con TDD and Código Sostenible). He is also the Founder of Savvily, a publisher specializing in tech books. Carlos will start off by sharing the four important traits of well-maintained software and examples of what maintainable tests are. He will dive into the benefits of mutation testing and exploratory testing, why engineers should advocate for a TECHNICAL_DEBT.md file in their git repository, why software engineers should aim to reduce the technical burden for their product team, services that Lean Mind offers, his latest book, Código Sostenible, and how to be a good guest in another team's codebase. Stay tuned for that and so much more!Book Recommendations:Nonviolent Communication by Marshall RosenbergHelpful Links:Carlos on LinkedInCarlos on GithubCarlos on TwitterHis Websitehttps://leanmind.es/Subscribe to Maintainable on:Apple PodcastsOvercastSpotifyOr search "Maintainable" wherever you stream your podcasts.Keep up to date with the Maintainable Podcast by joining the newsletter.
