Justin Yang

I am a Senior Software Engineer with over 10 years designing, building, and supporting large-scale, mission-critical platforms across telehealth, eCommerce, and cloud-native systems.

At Amazon, I designed and delivered a telehealth platform using Java/Spring Boot microservices on AWS, built end-to-end patient workflows, integrated video and payments, and operationalized AI prototypes into production services.

Previously at Walmart I developed high-traffic eCommerce features, search and personalization enhancements, and real-time data pipelines, improving stability and customer experience during peak events.

I focus on simplifying complex problems, improving system resiliency, mentoring teams, and driving cross-functional alignment to meet security, compliance, and operational goals.
