I would define API contracts and the data model early, implement migrations and backend validation, then build the React experience against stable interfaces. I would use code reviews, automated tests, observability, and a staged rollout to validate the feature safely in production. What are the key security considerations when implementing an OAuth 2.0 authorization flow and SSO integration? I would use the appropriate flow for the client type, typically Authorization Code with PKCE for browser-based applications. I would validate redirect URIs, state and nonce values, token issuer, audience, signature, expiry, and scopes, while keeping credentials and refresh tokens out of client-side storage where possible. Secrets should be managed through approved credential systems, and the integration should have audit logging, least-privilege scopes, and clear token revocation behavior. How do you structure a NestJS service to remain maintainable as the application grows? I prefer clear module boundaries aligned to business domains, with controllers kept thin and application services responsible for use cases. Domain logic should not be tightly coupled to database or third-party providers, so repositories and adapters can isolate infrastructure concerns. Shared contracts, validation, consistent error handling, tests, and dependency injection help preserve maintainability as teams and services expand. Describe how you would troubleshoot a production issue in a Kubernetes-hosted application. I would first assess user impact and stabilize the system through rollback, scaling, or feature-flag controls if needed. Next, I would inspect application logs, metrics, traces, pod events, deployment changes, resource limits, and dependency health to form and test a hypothesis. After resolving the issue, I would document the root cause and implement preventive actions such as alerts, regression tests, runbook updates, or infrastructure configuration changes. How would you approach bootstrapping a new squad or system from scratch? I would establish the problem statement, success metrics, ownership boundaries, and a thin vertical slice that delivers value quickly. I would align the team on architecture principles, development workflow, quality gates, environments, observability, and security expectations without over-engineering the initial release. Regular demos, technical decision records, and iterative feedback would keep the squad aligned while allowing the system to evolve based on real needs. Opportunity details ## About this role.
