IT Engineer II @ Kaiser Permanente

About

Backend engineer with 2+ years of hands-on experience building and scaling production APIs and event-driven systems using Node.js. I’ve worked on backend services that integrate multiple internal and external systems, optimized data-heavy queries, and implemented asynchronous workflows using Kafka. My experience includes designing role-based access control systems, integrating third-party APIs, and deploying serverless components on AWS. I’m backend-focused by strength, with working frontend experience for integration needs. Currently exploring backend and platform-leaning roles where system design, reliability, and scalability matter.
