As the Lead Architect for the Azure Messaging team, he helps run platforms like Event Grid, Service Bus, and Stream Analytics. He also shapes protocols like AMQP, MQTT, and CloudEvents in working groups like OASIS and CNCF. Recently, he has been focusing on JSON Structure—an IETF spec he authored—and the strange quirks of timekeeping in sports analytics data. With nearly 30 years in software development, Clemens has seen the same computing fashions come and go repeatedly. He admits he still writes too much code for an architect. ## Past Sessions ### World Congress 2026 Europe · July 8, 2026 Berlin, Germany - [Introducing JSON Structure](https://www.wearedevelopers.com/videos/100219-introducing-json-structure) · 30 min · 🎥 Watch recording - [What time is it?
