Hi, I'm Crystal Zhu, a Backend Engineer specializing in Java and Spring Boot microservices, API integrations, and workflow systems. I love building clear, maintainable, and reliable backend architectures that scale as complexity grows. I’ve worked on projects where correctness, validation, auditability, and dependable system behavior were critical, including external API integrations and back-end-enforced workflows. I aim to deliver robust backends that remain clean and safe to evolve as requirements change.…Hi, I'm Crystal Zhu, a Backend Engineer specializing in Java and Spring Boot microservices, API integrations, and workflow systems.
