United StatesWhat I'm looking for
I am a Senior Full Stack JavaScript Engineer with 12+ years building modern web applications using React.js, Node.js, TypeScript, and component-based design systems, with strong domain experience in healthcare, fintech, and civic platforms. I deliver accessible, pixel-accurate frontends, secure REST and GraphQL APIs, reusable UI libraries, and have hands-on experience integrating LLM/AI features into scalable production systems.
Throughout my career I have led frontend and full-stack projects—from real-time medical transcription and AI ambient scribe tools to payment API suites with multi-acquirer routing and robust webhook delivery systems—improving onboarding, reducing claim rejections, and enabling automated campaign and transcription workflows. I prioritize accessibility, reliability, and automated testing in CI/CD pipelines while leveraging cloud platforms (AWS/GCP/Azure) and container orchestration to deliver resilient, high-performance products.
