Full-Stack Developer
Location Seoul, South Korea 🇰🇷 Email wldnjsl2001@gmail.com Mobile +82-10-4688-5964 GitHub github.com/qorjiwon

A full-stack developer with 8 awards at on- and off-campus SW competitions and hands-on startup internship experience, who has grown by taking the lead across the entire product lifecycle, from planning to full-stack development, architecture design, deployment, and operations.

Most recently, I served as a teaching assistant for a hands-on AI Agent program for presidents and executives of Samsung affiliates, coaching them on work automation and website building with Claude Code and Gemini; the program ranked No. 1 in satisfaction among all in-house AI training, with the teaching assistants rated especially highly. During my internship, my smooth communication and diligence earned me the reputation of "a teammate we'd definitely want to work with again," and enough trust that the CEO personally offered to recommend me to other companies.

With the persistence to see a goal through once I set it, I turn failures and unexpected situations into stepping stones for growth and always create new opportunities for myself. In a culture that learns smartly from failure and keeps moving forward, I hope to make meaningful change together with the company.

Award-Winning Projects

DDOBAK 2025 SW-Centric University Digital Competition — Outstanding Award (SW Category)
May 2025 – Aug 2025 · Frontend (WebView) development + RAG-based contract-analysis pipeline design

A service that flags risky clauses in contracts using generative AI. Selected as the sole representative team out of 6 through an on-campus proposal pitch, then competed in the national competition

Next.js Spring Boot AWS Bedrock OpenSearch Claude 3.5 Sonnet Upstage Document Parser RAG
  • Compared 5 OCR engines and adopted Upstage Document Parser for its strong detection and table recognition; extracts contract text via OCR and lets users review and correct the results themselves
  • Designed a RAG pipeline that vector-indexes statutes and precedents in OpenSearch, with Claude 3.5 Sonnet judging toxic clauses and their risk levels
  • Prevents personal-data leakage by masking sensitive information in the contract before upload
  • Automatically finds toxic clauses, presents the risk level and rationale for each, and delivers the full result as a summary report

  • Built as a Chrome extension so users can get recommended problems right inside Baekjoon
