As a former Senior BE Engineer, I led several projects and teams. I used to build Chatbots for one of the first and most innovative companies for voice in Europe, that is Alexa Dev Partner and I did this in cooperation with a Google Expert Dev for Assistant (one of 40 worldwide), which enabled me to always have the latest technological insights. I wrote scientific work about Best Practices and Design Patterns for Voice User Interfaces and I do a lot of knowledge transfer and workshops on the topic to enable people to build good bots and to prevent them to fall for marketing magicians.
