Led backend migration of a staffing platform from monolith to microservices (Node.js/TypeScript), designing CQRS event-driven architecture with MongoDB projections for decoupled, independently scalable read/write models.

Engineered automated medical-claim verification workflows (Node.js + React.js), reducing manual processing by 40% and per-claim review time from 15 min to 5 min (67% gain). Integrated OCR-based document extraction pipeline with third-party APIs, enabling structured data ingestion from unstructured medical forms at scale. Optimised MongoDB aggregation pipelines and indexing strategies, cutting report generation time by 50%; implemented Redis caching to improve API throughput and reduce dashboard latency under concurrent load.
