Duration: 2023-01 ~ 2025-12 (ongoing)

Redesign and major work on the payment and authentication layers of a mobile game platform, under NDA.

  • Root-cause analysis and firewall policy fix for game-server item-grant timeouts
  • Influencer marketing API development and client integration
  • Mobile payment library updates
  • Payment flow redesign — “consume-then-charge” model
  • Google authentication migration (AuthorizationClient)
  • Ongoing SDK and OS update handling
