Vaughn and John discuss API portfolios and the increasing number of APIs being made available for public consumption. From John's deep knowledge and background in APIs, the timeline of early to contemporary technologies is considered for perspective. From there, they discuss monetization of strategic APIs using his innovative HyperCurrent product. In their dialogue, API First, REST, GraphQL, gRPC, asynchronous message-based and event-driven, the future of APIs and API products, as well as using APIs while applying DDD are covered. It's an opportunity to tap the knowledge of a long-time API design and tools expert.John D'Emic is the CTO and Co-Founder of HyperCurrent, the leading Enterprise API Monetization Platform. He is an architect, full-stack developer, and author with over 20 years of experience. Besides co-authoring both editions of Mule in Action, John has published numerous blogs, articles, and white papers.

Vaughn discusses generative AI with Cassidy Williams (@Cassidoo) regarding the SaaS AI product that she and her team have developed. They cover the challenges of generative AI that supports accuracy in content repurposing, such as: customers don't want content generated as a talk transcript with all images from the speaker's slide deck. Customers want the talk repurposed to contain the most salient points and related images that are suitable for, e.g., a blog post. What qualifies software as an AI, and what tools can help software engineers make the leap to AI application development? The two also discuss the good, the bad, and the ugly of ChatGPT, and how ethical companies can develop AI products with trustworthy ethics.Read our Contenda-generated blog post "Reactive DDD Modeling Uncertainty" and try Contenda for yourself at: https://contenda.co

After saying "ciao for now," Greg spontaneously continued the discussion, going into more details about book authoring. This turned into an interesting conversation about book writing experiences, but off topic from the initial podcast. You may still find it fun and informative.

He has 15+ years of varied experience in computer science from embedded operating systems to business systems and he brings a pragmatic and often times unusual viewpoint to discussions. 

With several great books on API design already on our shelves, this one stands out as a hefty pattern language and catalog for API designers. It's chock full of about everything you could need to design an industrial-strength API. Our discussion steps through the pattern writing process, including working as a team of five industry and academic professionals. Learn insights from one of the book's co-authors and pattern writers—a software industry practitioner—including his favorite and most challenging pattern in the book.Daniel Lübke is a Software and Business Process Architect working at Digital Solution Architecture GmbH in Hanover, Germany. He received his PhD in Software Engineering in 2007. Since then he is working as a consulting and coding software architect in client projects.
