Hi, I’m Sungmin Park, a Frontend Engineer focused on building production-grade web products with a passion for high-clarity UIs and turning messy business logic into maintainable systems. I’ve shipped products from early ideas to full platforms, wearing both individual contributor and system-builder hats to keep the whole project moving forward. I’ve led the charge on complex UI and content workflows, pairing design intent with solid engineering fundamentals. I’ve delivered CMS/LMS/B2C platforms and optimized real-world workflows in learning-management and content-authoring domains. I’m hands-on with problem solving, comfortable owning legacy cleanup, production stability, and long-running operational issues while collaborating across design, product, and backend teams.
