PROFILE

Jinsoo Jeong

Developed and delivered two core features over two months, focusing on deployment automation and scalable infrastructure for the langwatch/langwatch and langchain-ai/helm repositories. Built a Helm-based deployment and CI release workflow for LangWatch, introducing Helm charts for multiple services and integrating GitHub Actions to automate releases, which streamlined deployments and improved environment consistency. Extended the Langsmith Helm chart to support dynamic autoscaling using Kubernetes HPA with custom metrics, enabling more granular resource management across services. Leveraged YAML, Helm, and Kubernetes to reduce manual intervention, accelerate onboarding, and enhance operational reliability for multi-service deployments without introducing major bug fixes during this period.
