Kai Wähner - Technology Evangelist (Big Data Analytics and Middleware)

Welcome to my website. My name is Kai Waehner. I live near Erlangen, Germany and work as Technology Evangelist for Confluent - a Silicon Valley startup focusing on the open source project Apache Kafka to build mission-critical, scalable, streaming infrastructures for tech giants, modern internet startups and traditional enterprises.

My main area of expertise lies within the fields of Big Data, Advanced Analytics, Machine Learning, Deep Learning, Integration, SOA, Microservices, BPM, Cloud, Internet of Things, Blockchain and Programming Languages such as Java, Scala, Groovy, Go, Python and R. I regularly write about new technologies, articles and conference talks on my blog. 

The following shows my previous and upcoming talks at international conferences, video recordings and articles I published.
