About Me

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

At Glassdome, I build calculation and time-series workflows for carbon accounting and industrial software, while also working on multi-tenant systems and backend performance. Previously, I worked on search, authentication, payments, and Korean NLP.
