自我介绍About Me

大家好，我是张人大，常驻深圳的后端工程师，拥有 5 年 Java/Spring 交付经验。Hello! I'm Renda Zhang, a backend engineer based in Shenzhen, China with five years of Java/Spring delivery.

专注在 AWS 与 GCP 上构建 API-first 微服务，结合 Kubernetes、Terraform、GitHub Actions/Argo CD 安全交付。I design API-first microservices on AWS and GCP, using Kubernetes, Terraform, and GitHub Actions/Argo CD to ship safely.

擅长建立端到端可观测性与性能防护体系，利用 Redis 与消息队列优化高并发链路。I build observability and performance guardrails end to end, tuning high-concurrency paths with Redis and message queues.

与前端团队共建商家控制台等产品，按需选择 SSR/CSR/渐进水合并贯通埋点。I partner with frontend teams on SSR/CSR experiences, instrumentation, and selective hydration for merchant-facing products.

持有 AWS 解决方案架构师（助理，2025 年 6 月）认证，本科毕业于美国明尼苏达大学计算机科学专业。I hold an AWS Solutions Architect – Associate (Jun 2025) and a B.S. in Computer Science from the University of Minnesota.
