I have developed a Front-end bug tracking system. In the first week of introduction, 1.77 million errors were fixed. It was introduced at LINE Dev Day. Many engineers are using this system to ensure stable service operation.
I belonged to the Infrastructure Database team and worked on the migration to AWS Redshift Spectrum. In order to switch data sources safely, we have created a SQL job that checks for differences in the data after modification, and we introduced scheme to notify when there was problem.
We are engaged in research activities on the operation of laboratory networks, lectures on papers related to network technology, research on information and communication technologies and operation of real networks.
