Senior software engineer on the Connected Vehicle Platform focusing on OTA updates, telematics ingestion, and fleet diagnostics. Led a centralized Node.js feature flag service for 2M+ VINs with multi-region cache invalidation, built a Redis-based distributed lock for OTA firmware rollouts, and created real-time telemetry dashboards with OpenTelemetry context propagation. Optimized PostgreSQL inventory queries, integrated SBOM attestation via GitHub Actions using OPA, and added an AI-powered predictive maintenance scoring module; drafted a disaster recovery runbook for cross-region database failover.

Contributed to migrating a legacy dispatch monolith to Node.js microservices using NestJS and the Strangler Fig pattern; built a real-time hazard notification engine with WebSockets; automated off-lease vehicle inspection workflows; resolved memory leaks in a geospatial service; integrated Auth0 PKCE flows; developed a Python data-scrubbing utility for PII anonymization; scaled vehicle configuration API with load balancing and blue-green deployments.

Clinical Data Exchange: built a Node.js claims eligibility validator with Fastify and JSON Schema; added PostgreSQL partial indexes and Redis caching to reduce latency; created a triage web interface for ER staff; orchestrated data aggregation workflows triggering PySpark jobs on AWS EMR; contributed to distributed transaction coordination for pharmacy benefits using the Saga Pattern with Camunda; wrote end-to-end tests with Playwright and Testcontainers; refactored provider search API to GraphQL to reduce payload.
