Mercari Advent Calendar 2020 is coming up!

Hello! I’m @kayoreena of the Mercari Engineering Office.

The year 2020 will be over in a month! How was your life in 2020?

We have our annual Advent Calendar event in December every year and we’ll be hosting it again this year!

We have both Mercari and Merpay Advent Calendar at the same time.
▶ Merpay Advent Calendar 2020 is here here

What is the Advent Calendar?

The original meaning of Advent Calendar is "a calendar that counts down to Christmas". Based on this custom, Advent Calendar is a public blogging event that people post a blog every day from December 1 to 25.

We’ll be sharing our knowledge of the technologies used by our engineers at Mercari and Merpay. We hope this Advent Calendar will help you to enjoy the days leading up to Christmas.
