Eric Huang

I’m a Senior Full-Stack Engineer with 11 years of experience building scalable SaaS platforms, AI-powered applications, and cloud-native distributed systems. I focus on turning complex capabilities into production-ready features users can trust—especially at enterprise scale.

At Zendesk (Senior Software Engineer, 04/2020–Present), I built AI-powered capabilities for customer support workflows using LLM technologies. I designed and implemented semantic knowledge search with Retrieval-Augmented Generation (RAG) and vector search, and I developed backend services exposing REST and GraphQL APIs for real-time agent experiences.

I integrated AI services with PostgreSQL, MongoDB, and Redis to optimize data retrieval, caching, and asynchronous processing, reducing API response latency by over 25%. I also built customer-facing interfaces with React, Next.js, and TypeScript, and deployed cloud-native microservices on AWS using Docker, Kubernetes, and Terraform for scalable, reliable CI/CD.

Previously at Fin (Software Engineer, 10/2014–04/2020), I developed conversational AI solutions that automated customer support using natural language understanding and machine learning. I improved performance by reducing average response time by 30% through indexing, caching, and query optimization across PostgreSQL, MongoDB, Elasticsearch, and Redis, and I delivered responsive AI administration and analytics portals for operational visibility.
