About


After graduating from university in 2022, I have been working as an Embedded SRE (Site Reliability Engineer), focusing on designing and operating cloud infrastructure.

I specialize in infrastructure automation, observability enhancement, and designing reliable architectures using Kubernetes, Istio, AWS, and Datadog. By improving observability, I have enhanced system operational efficiency, implementing automated anomaly detection using Datadog APM and custom metrics, collecting detailed JVM and Redis metrics, and optimizing service reliability through Istio traffic management. Furthermore, I have leveraged these data-driven insights for bottleneck analysis and performance tuning, leading to faster API response times and optimized system loads. Additionally, I have strengthened pre-release performance evaluation through load and failure testing, contributing to reduced operational costs and improved service stability. I also have experience leading cloud migration projects, with a strong ability to build scalable and maintainable systems.
