Context
A legal platform needed stable integrations with third-party systems while preserving clear internal domain boundaries.
Problem solved
Integration behavior was fragmented, making troubleshooting and feature iteration costly.
What I built
Designed a consistent integration layer with typed adapters, normalized error handling, and traceable request flow.
Technologies
- Node.js
- TypeScript
- Next.js
- REST
- OpenSearch
Outcome
Teams were able to iterate integration-dependent features with lower risk and faster incident diagnosis.
Architecture highlights
- - Adapter pattern for external providers with shared contracts.
- - Centralized integration logging and error classification.
- - Feature flags for safer rollout of provider-specific changes.
