- Day3 : AI/Data, Fintech, Blockchain, Developer Product, OSS, Product Management, Team & Process, Design, Others
In order to give you a fragmented view of the conference content, we have released the movies of pre-interviews with the speakers. Since it’s difficult to introduce all the speakers, we’ve included 8 speakers from AI/Data, Server Side LINE Platform, Security, Infrastructure, Server Side Application, Client, Frontend and Developer Product. We’ve picked up a speaker from each category and asked them to give us an outline of the session they were in charge of, as well as a subjective view of what LINE DEVELOPER DAY 2020 is all about.
