Dylan
Software Engineer. Graduated with a B.S. in Computer Science and Engineering with a 4.24/4.5 GPA from Sungkyunkwan University in South Korea. I build software across AI, robotics, the web, and mobile.
I'm a software engineer who likes owning problems the whole way through, from a robot's control loop to the UI/UX a user experiences.
Currently building AI and robotics software at Luxolis. Before that, RAG systems, LLM research, and full-stack products.

CurrentAI & Robotic Software Engineer
Luxolis · South Korea
- Built the whole welding automation stack, an Alpine.js UI on FastAPI with a C++ DRFL robot daemon, that drives a Doosan A0912 arm, a Raycus CFL laser, and a motorized turntable from one piece of software.
- Containerized our software into reproducible Docker services with automated build scripts, bundling MinIO, Redis, and SQL.
- Shipped a React Native app for Android and iOS with 3D spatial vision, checking package compatibility and running integration tests across the stack.

AI / Backend Engineer, RAG Pipelines
Saifly · United States (Remote)
- Took a compliance RAG pipeline from a zero baseline to recall@k 0.448 and MRR 0.382, using Docling chunking, pgvector retrieval, and an eval harness that tracked recall, precision, MRR, and NDCG.
- Built semantic chunking with clause-level embeddings and token-boundary limits, plus metadata-rich indexing so retrieval could actually be explained.
- Cut ingestion overhead with async batching, dedup, and incremental re-indexing.

Undergraduate Researcher
HLI Lab, Sungkyunkwan University · South Korea
- Ran cultural-bias evaluations across GPT, Llama, Qwen, Claude, and Gemini to see how their cultural priors and stereotype sensitivity differed.
- Proposed a value-based alignment framework that infers a model's values, corrects for bias, scores against World Values Survey data, and steers personas using Schwartz's value theory.
