Hi, my name is Mia, Jihyung Lee.
I am a frontend developer with 6 years of experience specializing in Angular and TypeScript, with a strong track record of building and improving large-scale commerce platform admin tools and B2B seller centers.
With a background in Graphic Design, I approach problems from a UX perspective โ defining requirements in collaboration with planners, designers, and backend engineers, and translating them into implementable structures.
I have led initiatives in monorepo migration, CI/CD optimization, and test automation to enhance team productivity and system reliability. I believe in simplifying complex domains into maintainable architectures that empower teams to ship with confidence.
- Kakao Commerce Admin & Seller Center โ Built and maintained internal admin and B2B seller center for Kakao Gift, TokDeal, and other B2C services, covering 10+ domains including orders, claims, messaging, ads, and CS platforms.
- Nx Monorepo Migration โ Led the consolidation of 12 multi-repositories into a unified Nx-based monorepo, reducing context-switching costs and improving team collaboration. Optimized CDN usage from 4.5TB โ 300GB.
- CI/CD & Test Automation โ Managed 31 apps via Jenkins multi-branch pipelines; introduced Nx affected-based parallel builds, cutting build time from ~30 min โ ~3 min. Set up E2E testing with GitHub Actions + Playwright.
- Legacy Platform Migration โ Led the long-term migration of order/claim legacy platforms to a new architecture with a gradual transition strategy.
- Kakao Friends Shop โ Developed client and admin FE for Kakao IP product e-commerce. Migrated React app to Angular, handled markup to i18n without a dedicated publisher.
- DJBB (DJ Black Bunny) โ A service to send letters with music to ring in the New Year. Handled planning, product design, and full-stack development (FE/BE). Over 1,900 cards were created after launch.
