Be Professional Day (BPD) with the Frontend Team!

Hi! I’m @sottar, a frontend engineer at Mercari.
The other day, Mercari’s Frontend Team held an offsite called Be Professional Day (BPD)!
Japanese is here

What is BPD?

This article has a good explanation about BPD. Basically, it’s a day where team members take on projects that they want to do, but can’t in their normal work.


Right now at Mercari, engineers belong to teams divided by domains, and development is done in each domain team. Because of this, frontend engineers don’t work together very often, and there are fewer opportunities to spend time together across different domain teams. The number of members has also increased, and newer frontend members haven’t had the chance to interact with frontend members of other domain teams.

Also, when you focus on only product development, you start thinking too much from a short-term perspective. But sometimes there are things that you can do to improve development efficiency and quality in the long term, even if it doesn’t help the product in the short term. We decided to hold BPD in the team as a way to pay back the technical debt we’ve accumulated in our usual rapid product development and as a chance to try out new technology.


Checking who wants to attend and deciding the date
In addition to all of the frontend members, we even had members of GOT, who usually provide support for our meetings, join us to work on frontend development! (What is GOT?)

We wanted to have as much time as possible to focus on work, so everyone decided what they were going to do in advance.
Arranging lunch and dinner
We didn’t want to make things confusing on the day of the offsite, so we arranged delivery for lunch, and used Uber Eats for dinner.

Day of the Offsite

Everyone getting comfortable as they work

At the end of the day, all team members presented what they did that day. Drinks were provided at the presentation, and we had a great time!

There were all kinds of presentations, from tools created to improve the efficiency of our normal work to trying out new technology we haven’t used before.

Wrap up

At BPD, we were able to work on things we usually aren’t able to do, and we were really pleased with the results.

It was the first time we held this event, so there were definitely things that could have gone better, but it was a good offsite, and we’re hoping to hold it again in the future.
