Kailu Hu

I’m a software engineer with 7+ years of hands-on experience building and supporting enterprise-scale full stack applications across retail, banking, compliance, automation, and corporate platforms. I focus on Java-based backend development—designing Spring Boot/Spring MVC microservices with clean code and maintainable architectures—while delivering responsive, data-driven user experiences with React.

At Walmart, I lead development of the DS Marketplace platform, creating Java Spring Boot microservices that handle business logic, validations, orchestration, and service integrations. I build and expose RESTful APIs, develop responsive React/Bootstrap/HTML/CSS/JavaScript interfaces for internal users, and support transactional and reporting workloads with PostgreSQL and MongoDB. I also implement Kafka-based asynchronous messaging to enable decoupled event processing and ensure security, compliance, and governance in an Agile/Scrum environment.

Previously at Microsoft, I designed a global compliance and reporting platform, building backend services with Java, Spring Boot, Hibernate, and REST APIs and creating React-based dashboards to improve usability. Before that at Citi Bank, I developed enterprise applications for automation and virtual desktop infrastructure, implementing RESTful services, SQL-driven operational tooling, and production support. I also completed a Java Full Stack Development Bootcamp covering Spring, Hibernate, microservices concepts, REST API development, SQL/MongoDB, and Kafka fundamentals.
