Experience

Infrastructure Engineering for S.RIDE

https://www.sride.jp/en

S.RIDE, a Sony group company offering a taxi service solution in Japan, tasked me with managing the server-side back-end infrastructure environment for the app. This project involved testing APIs and implementing daily and weekly updates using GitHub Actions for CI/CD. I successfully grew the infrastructure team for more than three years.

VMware Virtual Environment for NTT Docomo

From 2006 to 2011, I built, implemented, and managed two VMware test environments for BlackBerry's enterprise solution using a tower of rack from scratch. Those two virtual environments leveraged Microsoft Exchange Server and IBM Lotus Domino. I installed several Dell servers to a rack and installed and configured Windows Server, VMware, and BlackBerry's enterprise server. Then, BlackBerry clients were successfully activated in no time.

VoIP Project at NTT R&D

In 2004, I successfully led a project to test a VoIP and SIP system in four regions: Japan, Korea, the UK, and the US. The project required communicating with four regions using chat software or voice calls.
