Architecture

  • OAuth Login Flow

    The authorization-code exchange between a browser, your app, and an identity provider.

  • Microservices Architecture Map

    How an API gateway fans out to independent services, each with its own datastore, plus the async event bus wiring billing and notifications to order events.

  • Role-Based Access Control Model

    Users belong to teams and hold roles; roles bundle the permissions that actually gate an action — the object model behind most RBAC implementations.

Data

  • SaaS Multi-Tenant Schema

    Organizations, the users they employ, and the subscription/invoice chain that bills them — the shape most B2B SaaS apps start from.

Engineering

  • CI/CD Pipeline

    Commit through build, test, and deploy, with the failure path back to the author.

Operations

  • Support Ticket Lifecycle

    A helpdesk ticket from intake through resolution, including the reopen loop when a fix doesn't hold.
