About Me

I'm a backend engineer with 6+ years of experience building APIs, data-processing systems, and calculation workflows. I work primarily with Go, PostgreSQL, and Kubernetes, with production experience in TypeScript, GraphQL, and cloud-native infrastructure.

At Glassdome, I build backend services for carbon accounting and industrial software, including calculation, aggregation, and time-series workflows. I also work on multi-tenant authentication, authorization, and backend performance. Previously, I built systems for search, payments, authentication, and Korean NLP.
