About me
I'm Donggeun, a full-stack engineer building B2B SaaS high-availability systems at a Korean enterprise. Recently: an Apache Camel 2.x to 3.x migration across 13 libraries, an OpenJDK security upgrade, multi-node split-brain logic, and a legacy to Spring Boot + React migration.
I build:
- Web apps, front to back (Next.js, React, Node.js, Python)
- Cross-platform mobile apps (iOS + Android)
- Automations and data pipelines (Python + LLM APIs)
- AI features: chatbots, RAG search, summarization
Open source: KakaoAsset (real-time crawling, ElasticSearch, K8s).
What I deliver runs in production.
