LINE DEVELOPER DAY 2020 official website:

Since 2014, LINE DEVELOPER DAY has been the place for LINE to gather engineers and present the different challenges and projects it has taken on in various technical fields for its wide range of services.

Last year's program was a mix of sessions that mainly focused on technologies under the theme "Engineering," and sessions that offered practical perspectives to product development under the theme "Production" with topics such as web service technologies, UI/UX, and project management. Furthermore, attendees were able to participate in hands-on sessions to try coding using LINE's OSS, API, and other technologies, as well as visit booths and poster sessions to discover LINE's services at a deeper level.


First ever online event, streaming a record number of more than 150 different content over three days comprised of technical presentations, panel discussions, and more

In response to the spread of the novel coronavirus (COVID-19), LINE DEVELOPER DAY 2020 will deliver all of its sessions online for all three days. The program will kick off with LINE's CTO Euivin Park's keynote speech on the company's technology strategy and vision, describing technology initiatives in response to the recent social circumstances and changes in the environment surrounding LINE. Presentations and panel discussions will follow under the same theme, focusing on the challenges and knowledge gained in various fields including AI, data, fintech, infrastructure, server-side, and front-end technology. Furthermore, a diverse group of more than 30 guest speakers from Japan and abroad will be presenting and moderating some of the panel discussions, making this year's program the biggest in history with the plan to stream more than 150 different content.
