Hi, I'm Woo

Spatial Data Builder · Spring Backend Engineer · System Design Enthusiast

I build services that turn complex data into real products — from geospatial processing pipelines and Spring-based APIs to deployment workflows, operations, and architecture.

---

Current Focus

• Building spatial data services that connect data processing, storage, and visualization
• Designing Spring Boot backend systems with clear responsibilities and maintainable structure
• Improving CI/CD pipelines with Jenkins, GitLab, and quality automation
• Expanding toward MSA, authentication, Redis session/cache, and scalable service architecture
• Exploring AI-assisted development workflows and practical service integration

---

Selected Work

• CesiumReact
  3D geospatial visualization with React and Cesium

• ktds-23-pms-react-server
  Frontend implementation for a PMS service

• ktds-23-pms-reactVer
  Spring-based backend implementation for PMS

• ktds-23-pms-batch
  Batch/data-processing component for service operations

• 98woo.com
  Technical writing on backend systems, AI services, DevOps, network, and architecture

---

What I'm Building Toward

• Reliable backend services that survive real operations
• Data pipelines that make spatial information actually usable
• Development workflows that reduce repetitive work through automation
• Architectures that connect code, infrastructure, and operations into one coherent system
