I'm a Senior Software Engineer with 4.8+ years building enterprise-scale backend systems at Optum (UnitedHealth Group) — one of the world's largest healthcare technology companies. My work spans the full backend lifecycle: I've led the design of a GraphQL aggregation layer that reduced API complexity by 40%, architected OAuth2/JWT-based session management for secure multi-tenant access, and modernised 10+ legacy Scala services to Java — improving long-term maintainability across enterprise codebases. On the data and infrastructure side, I've built Kafka-driven real-time event pipelines, optimised PostgreSQL/MySQL queries at scale to cut infrastructure costs by 40%, and designed CI/CD pipelines on Docker and Kubernetes for consistent enterprise deployments. 🔧 Core stack: React .
