You will design it, build it, test it, deploy it, document it, and support it in production. * If you need someone to hand you tickets and watch over your shoulder, this is the wrong role. ## Related Videos - [Web APIs you might not know about](https://www.wearedevelopers.com/videos/281-web-apis-you-might-not-know-about) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Grappling With Clunky Old Software?
