Authentication & Authorization Systems

Common Challenges & Technical Drivers

• Monolithic architecture bottlenecks preventing independent team feature releases.
• Synchronous API chains causing cascading latency and failure amplification under load.
• Lack of standardized error handling, correlation IDs, and structured logging.
• Difficulty scaling stateful applications across multiple availability zones.

What Is Included (In-Scope Deliverables)

• Cloud-native backend service and API development adhering to 12-factor principles.
• Event-driven messaging integration using queues and publish/subscribe brokers.
• Distributed tracing instrumentation with OpenTelemetry and correlation IDs.
• Automated unit, integration, and contract test suites with mock interfaces.

Scope Boundaries & Transparent Exclusions

• Front-end visual UI/UX graphic design creation (we engineer backends and APIs).
• Third-party API consumption charges (e.g. OpenAI, Stripe, Twilio fees).
• Content marketing writing or end-user customer support.
• Maintaining legacy on-premise proprietary mainframe applications.

Tangible Engineering Deliverables

• Clean, version-controlled TypeScript / Go / Python service repositories with Dockerfiles.
• OpenAPI 3.1 specification contracts and interactive Swagger UI documentation.
• Automated test suites with high code coverage verifying business logic and edge cases.
• Deployment manifests and environment configuration variable templates.
