He focuses on connecting APIs with large language models, giving isolated AI the ability to retrieve information and take action. Instead of treating AI as a standalone brain, Johannes wires APIs as active "organs" that let models execute tasks. His work covers agentic AI, function calling, and Anthropic's Model Context Protocol. He relies on tools like Postman Toolgen and TypeScript to help developers assemble custom agents—automating everything from drafting architecture descriptions to transforming Confluence pages into Berlin techno songs. ## Past Sessions ### World Congress 2025 · July 9, 2025 Berlin, Germany - [Operation FrankenstAIn - Let's build an agent with your own APIs](https://www.wearedevelopers.com/events/world-congress-2025/sessions/474-operation) · 120 min ## WeAreDevelopers LIVE - [Branch your database like your code: How schema changes and pull requests go hand in hand](https://www.wearedevelopers.com/videos/350-branch-your-database-like-your-code-how-schema-changes-and-pull-requests-go-hand-in-hand) · Johannes Nicolai, Lilli Seyther-Besecke ## Links - [X](https://twitter.com/pulipan1) - [LinkedIn](https://www.linkedin.com/in/johannes-nicolai-b508208) - [Blog](https://blog.postman.com/)
