BACKEND · AI SERVICE · EDGE-AI ENGINEER
Building projects that turn curiosity
across backend, AI, and games into reality.
Spring Boot and FastAPI APIs, AWS media pipelines, GraphRAG voice services, and real-time RTSP/NPU monitoring: this is Hwang Seon-woo's development portfolio.
Four Core Projects
Problems, implementation scope, and validation evidence I led.
BACKEND · AI · SYSTEM CASE STUDYJeonbuk Provincial Voice Chatbot
A public voice-information service that retrieves provincial and municipal data with GraphRAG and delivers it through STT/TTS.
BACKEND · AI · SYSTEM CASE STUDYSmart CCTV Fall Detection
An Edge-AI monitoring project that reduces nursing-home RTSP false positives with pose, detector, and site-context zero-shot validation.
BACKEND · AI · SYSTEM CASE STUDYStreaming API
A streaming service connecting React, Spring Boot, AWS S3, Lambda, and MediaConvert.
BACKEND · AI · SYSTEM CASE STUDYE-Commerce Backend
A Spring Boot, JPA, and Querydsl service covering product browsing, cart, orders, and payment verification.
Implementation Strengths
Spring Boot, FastAPI, REST APIs, JPA, Querydsl, MariaDB, PostgreSQL
STT/TTS, GraphRAG, LLM agents, SSE/WebSocket, Computer Vision
AWS S3 · Lambda · MediaConvert, Linux, RTSP, NPU model conversion and deployment
I document logs, thresholds, retries, API boundaries, and domain limits as implementation evidence.
