Experienced engineers actively maintain the test code while making it easy to refactor and change, so the code has relatively low technical debt.

■ Infrastructure
The infrastructure is mostly built on AWS and utilizes EC2, S3, CloudFront, lightsail, etc. DB is MySQL, KVS is memcached and Elasticsearch, and reverse proxy is nginx.
Currently, there is room for improvement, such as the server configuration being excessive due to changes in market conditions.
