+    "bio": "Nikita is a big fan of asynchronous architecture. At one time, he worked a lot on various asynchronous services and faced the main problem of integrating them - the lack of documentation. Therefore, he created a new generation python framework - FastStream, which generates AsyncAPI schema from the service code automatically. Now he promotes Event-Driven architecture, AsyncAPI, and FastStream in all his public talks and articles.",
