LTS2/README.md

Woojin (Jin)

Backend engineer based in Korea. I care about reliability, performance, and observability in production systems.

Open Source Contributions

  • oh-my-opencode
    • Pull Request: Add unit tests for the shared deep-merge utility (plain object detection, deep merge behavior, array replacement, unsafe key protection, max depth behavior)

What I focus on

  • Building resilient backend services with clear boundaries and predictable behavior
  • Improving test quality to prevent regressions in shared utilities and core logic
  • Performance and failure-mode thinking (timeouts, throttling, backpressure, monitoring)

Tech

  • Java, Spring Boot, JPA, Python, TypeScript
  • Kubernetes, AWS
  • Monitoring: VisualVM, Prometheus, Grafana
