The challenge
Build a web application that connects external gaming identity with player-specific store state, virtual balances, item management and card-payment checkout while keeping privileged payment operations on the server.
What OSYSTIC built
OSYSTIC implemented Steam OpenID authentication, Django ORM persistence, and Stripe Checkout with webhook integration, supporting player profiles, virtual coin packages, transactions, game items, and player slots.
Engineering Highlights
- Integrated external gaming identity with application-specific player profiles.
- Kept privileged payment operations behind the server-side application boundary.
- Modelled player/store state through explicit persistent domain entities.
- Separated user-facing store workflows from administrative management surfaces.
- Hardened runtime secret handling during repository modernization.
Capabilities
- External Identity Integration
- Secure Payment Architecture
- Domain State Modelling
- Administrative Workflows
Public Evidence Boundary
Client identity, private source, Steam IDs, Stripe identifiers/secrets, production database content and private operational details remain excluded.
Outcomes and validation
- Successfully delivered integrated external identity, server-side payment boundaries, and domain-specific player and store state management.
