Backend-focused software engineer and product builder working across AI, data, and production systems.
CS student at Chung-Ang University, graduating in August 2027.
I work across the path from raw data to production: ingestion and normalization, APIs, async processing, model integration, deployment, observability, and debugging. I care about the part after a demo works—making the system reliable enough to run.
