Episode 23 of Tech Leadership with Fexingo dives into the surprisingly high-stakes world of API style guides. Lucas and Luna discuss why a well-crafted guide is more than just naming conventions — it's a tool for reducing cognitive load, speeding up onboarding, and preventing production incidents. They break down specific examples: the difference between RESTful and RPC-style endpoints, the hidden cost of inconsistent error responses, and how one team at a mid-size fintech cut integration time by 40% after adopting a shared guide. The conversation also touches on the tension between strict rules and developer autonomy, and why a style guide should be a living document, not a PDF that collects dust. Whether you're a CTO, an engineering manager, or a senior IC trying to persuade your team to standardize, this episode offers concrete arguments and practical starting points.
