AI / LLM
I design the preprocessing, chunking, embedding, and citation flows that drive RAG retrieval quality inside real products.
I began in data analysis and now build the backend and RAG flows behind production generative AI.
I started out in data analysis and now build Generative AI (K-Bot), a production AI feature in K-System AI, at Younglimwon Soft Lab. I work mainly on Python/FastAPI backends, RAG retrieval with Vector DBs and embeddings, and Azure-based data pipelines — and when needed I build the frontend myself with Svelte and TypeScript.
When I take on a feature, I see it through end to end — reproducing the problem, designing, implementing, and shipping. I reproduce issues precisely, separate state from boundaries, and document the process so it can be reused.
Rather than staying within a single technology, I am growing into an engineer who connects data, backend, and AI to solve real problems. I want to treat technology not as a mere means of implementation, but as a tool to resolve the problems my teammates and the business face more clearly.
I design the preprocessing, chunking, embedding, and citation flows that drive RAG retrieval quality inside real products.
APIs, data flows built to be reproducible and traceable.
Storage structures and migrations designed for search, embeddings
I deploy the embedding API on Azure App Service and orchestrate document-ingestion pipelines with Logic Apps and Blob, connecting RAG services reliably to production.
I connect backend flows into trustworthy UX, such as verifying the sources behind RAG answers.
