Backend-oriented software engineering student at Chung-Ang University.
I build backend systems from messy inputs to production behavior: data collection, preprocessing, API design, async processing, service integration, deployment, and validation.
- Recommendation infrastructure and backend systems
- Product workflows that need reliable data and runtime boundaries
- Production debugging, quality gates, and deployment verification
- Virtual try-on, image-processing, and data pipelines
