Full Stack Engineer at CVS Health

Architected a full MERN-stack pharmacy case management platform consolidating prescription refills, delayed requests, missing member documentation, and unresolved care cases into a single real-time operational workflow for 200+ agents, replacing spreadsheet-based processes. Integrated an LLM-powered case summarization engine using OpenAI API and RAG to summarize member and prescription context, reducing average handle time by 30%. Built LLM prompt-engineered intent classification with embedding similarity scoring to auto-categorize and route support tickets to correct team queues with zero manual tagging. Implemented 15+ secure RESTful API endpoints with Node.js/Express.js exposed via AWS API Gateway (usage plans, throttling, validation) for member intake, Rx status tracking, provider lookup, case updates, and immutable audit trails, reducing inter-team handoffs by 40%. Enforced HIPAA security with short-lived JWT access tokens, OAuth2 refresh flow, fine-grained RBAC scopes, PHI field

Modernized a military simulation and virtual training platform by migrating legacy jQuery/AngularJS screens to a Next.js + React TypeScript architecture with SSR/SSG and code splitting for 10K+ daily active users. Built pixel-accurate, responsive UIs from Figma/Adobe XD using React, Tailwind CSS, and shadcn/ui for mobile-first tablet/field-device access. Developed a Storybook component library (50+ documented components) to standardize UI and cut development time by 40%. Decomposed a monolithic Node.js app into independently deployable Express.js microservices behind AWS API Gateway for isolated scaling and fault containment. Built internal .NET Core C# microservices for simulation configuration and license validation exposed via API Gateway with environment stage routing.

Software Engineer at Lumeris

Migrated high-volume patient data retrieval from S3 flat-file lookups to a DynamoDB single-table design with optimized GSI/partition strategies, delivering 300% faster response times for critical healthcare endpoints. Built cloud-native services on AWS ECS (Fargate), EC2, Lambda, and DynamoDB for ingestion, care gap reporting, and population health analytics with CloudWatch monitoring. Developed Java 17 Spring Boot REST APIs using layered Controller/Service/Repository architecture with Hibernate ORM for PostgreSQL and deployed via Docker behind AWS API Gateway with throttling and request/response mapping, improving backend processing by 20%. Built C# .NET Core transformation services to normalize/validate provider feeds, handling schema versioning and backward-compatible migrations before ingestion into DynamoDB. Engineered serverless ETL pipelines using Python Lambda, Pandas, and Apache Spark on EMR with multithreaded batch processing to validate/transform/load large healthcare datase
