PROFILE

Jinsoo Jeong

During a two-month period, Jisung Jeong developed and delivered deployment automation and autoscaling features for the LangWatch and Langchain Helm repositories. For LangWatch, he built a Helm-based deployment pipeline, introducing templated Helm charts for multiple services and integrating GitHub Actions to automate releases, which streamlined environment management and reduced manual intervention. In the Langchain-ai/helm repository, he extended the Langsmith Helm chart to support dynamic autoscaling using Kubernetes HPA with custom metrics, enabling more responsive resource allocation across services. His work demonstrated depth in CI/CD, Kubernetes, and Helm, focusing on maintainable, scalable infrastructure without addressing bug fixes during this period.
