Backend-focused full-stack engineer. At Moty (Seoul) I'm the sole engineer for everything except the mobile apps, owning it end to end β 183 REST endpoints across 22 domains (Java 21, Spring Boot 3), a trainer-facing analytics web app and admin console (Next.js), Terraform-managed AWS, and zero-downtime CI/CD.
My production work lives in private company orgs, so instead of code, I document the architecture β see saas-architecture-notes.

- πΈ Cut AWS costs 58% ($493 β $209/mo) β Graviton migration, self-hosted PostgreSQL/Valkey
- π Zero-downtime deploys β GitHub Actions OIDC β ECS, circuit-breaker rollback, Flyway expand-contract
