DMM meetup #12 Participation Report

DMM meetup #12 DMM新規事業を支える技術 - connpass

Below, I’ve transcribed the presenter names and titles from the event page and recorded my notes from listening to the presentations as a participation report. (Honorifics omitted)

Yuki Matsumoto / DMM.com LLC CTO "DMM's Current Status and the Vision We Aim for Through Engineering"

DMM TECH VISION -DMMのテックカンパニー化に向けた、CTO松本の3年後に向けた取り組みを公開!!- - DMM inside

Below are keywords that personally stuck in my memory, in bullet points.

• Enhance business with technology
• Technical debt accumulates after running a business for n years. That's inevitable.
• Basically, each business has free technology choice. However, we ask them to be conscious of Disposability.

Yasuomi Takano / Infratop Inc. "About wanting to grow educational services"

Being able to change careers as an engineer in 3 months is amazing.

In our company’s case, we train non-engineers to become engineers for job changes, but it takes about 3 months of training followed by 3-6 months of OJT, so this seemed incredibly fast.

Hiroya Hinomori / Aquiz Business Division iOS Engineer "To Provide Value to Users at Maximum Speed"

• CI/CD → Using Bitrise
• Data → Redash

“They say data-driven, but how do you actually do it?”

Michito Sawa / life+ Business Division Engineering Manager "About Menus"

AIで献立作り!?　DMMが提供する献立提案アプリMENUSの中の人たち - DMM inside

• Analysis of existing specifications is important
• Data visualization is important

My personal impression is that I hope “a world where we become healthy unconsciously” comes soon.

Ryusuke Kumida Life Ending Business Division Development Manager "Containerizing a Large-Scale System with 5 Million Monthly PV"

I had the impression that containerization made the architecture more modern.

I think it’s inevitable that the deploy flow with AWS CodePipeline + CodeBuild becomes slower than git pull deployment. The benefits gained from it are greater.

That’s all from the Gemba.
