Experience

Built frontend applications for client and internal projects. On the internal attendance product (몰입도), I also worked on the Koa/MySQL backend and the attendance rules behind it.

• Developed frontend user interfaces and internal web applications across client and internal projects.
• Contributed Koa and MySQL backend development for an internal attendance management product.
• Translated attendance-domain rules into application state: active-session checks, multiple work and break periods, and a 06:00 operational boundary for overnight workdays.

Built frontend interfaces on top of APIs and real-time streams developed by senior and backend engineers.

• For Daegu Smart City, integrated exposed APIs and real-time streams into frontend visualization and interface behavior.
• For RUTA40, implemented the React UI and HTTPS control integration on a real vehicle while the embedded and backend teams provided the module and control API.

Interpreted and translated between Korean and English, and automated the repetitive parts of the translation workflow.

• Built JavaScript utilities for Hangul text decomposition and dictionary-driven Korean-to-English replacement actions.
• Built VBA utilities for file renaming and Windows Explorer workflow actions to reduce repetitive translation steps.
• Coordinated permitted execution methods with on-premise Korean and U.S. IT teams in an environment where PowerShell was prohibited.
