At TideSquare, I own end-to-end features for BTMS business travel, spanning air and hotel booking, payments, and company and agency administration across React, Quarkus, and MySQL applications.
I've implemented enterprise authentication through SAML 2.0, Google OAuth, and Amaranth SSO, and delivered reward-mile, corporate payment-card, booking, validation, voucher, invoice, cancellation, lockout, and audit-log functionality. I collaborate with the Korea product team through Jira and translate Figma design-system work into production UI.
For HanjaHero, I've built AI learning features including question explanations, a vocabulary chatbot, and speaking practice using FastAPI, PostgreSQL, LLM prompts, TTS integrations, React, Ant Design, and TanStack Query. I also build personal products, including a Tauri desktop MySQL client and a full-stack Next.js blog CMS.
