Haruka Abe (Tokyo, Japan)
Profile
I am a backend engineer with 5 years of practical experience. I have handled various workloads, from large-scale backend services for popular IPs to common platforms for hybrid casual games. My strength lies in being able to build services comprehensively with ownership, from API design to infrastructure design and deployment. Additionally, I can identify and address issues within the team as they arise. For example, in Project Sekai, I implemented a management console from scratch to reduce the load of the scenario team.
