Hi, I'm Nabin Kim

M.S. in Computer Science (Machine Learning) from Georgia Tech.

I build research software and AI-enabled systems, with a focus on backend infrastructure, evaluation, healthcare and behavioral data, and reliable software for research workflows.

My work spans FastAPI/React applications, data and ML pipelines, containerized services, observability, and reproducible research systems.

Selected Projects

Full-stack RAG system with FastAPI, Weaviate, Docker Compose, Prometheus/Grafana observability, health checks, CI/CD, and user feedback.

Synthetic-data healthcare-AI research prototype (FastAPI, Next.js, SQLite). Implemented hybrid retrieval, then measured it on a frozen 20-query / 49-chunk fixture: query expansion hurt, MiniLM/hybrid underperformed BM25, and the demo default followed that evidence. Corpus provenance documents the 15/14 source split. Not for clinical use; does not claim HIPAA compliance.

Modular behavioral-data research pipeline for Reddit collection, LLM-assisted classification, sentiment analysis, topic modeling, statistical analysis, and reproducible evaluation.

Clinical decision-support prototype integrating FastAPI, SMART on FHIR, structured EHR data, and LLM-assisted triage.
