Mobile Game Platform: Payment and Auth Redesign

Mr. Latte ∙ Software Development Expert

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

What I built

• Google auto-cancellation (3-day unconsumed) handling, ongoing manual verification flow
• 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
