Browser Expert | Chromium, C++, Full-Stack Web, UI/UX and APIs

I am a browser and full-stack product engineer specializing in Chromium-based systems, responsive web interfaces, debugging, and end-to-end product delivery.

At LG Electronics, I worked on the Chromium-based webOS Browser, building browser UI in C++, leading History and Bookmarks interface work, and implementing portrait and drag-and-drop touch interactions for LG StanbyME. I also contributed to a monetized New Tab Page with advertising and weather API integrations.

I now build and improve web products across React, Next.js, TypeScript, Node.js, REST APIs, authentication, payments, reservations, and responsive UI/UX. My portfolio includes five founder-led products covering consulting, marketplaces, interactive games, booking, commerce, and experiential services.

I am best suited to clearly defined problems such as an incomplete frontend, browser-specific bug, responsive layout issue, API integration, compact backend feature, product rescue, or a complete fixed-scope website build. I work from reproducible evidence and an agreed completion point, then provide testing notes and a clear handover.

Work Terms

Available for fixed-price milestones or hourly work. I prefer a written scope, relevant URLs or repository link or project files, and reproducible examples before work begins.

Typical workflow: confirm the affected user path and acceptance criteria; reproduce and diagnose the issue; implement the agreed change; test across relevant browsers and screen sizes; deliver a concise change log and handover notes.

Communication is available in English or Korean through Guru. I provide progress updates at agreed milestones and flag scope changes before doing additional work. Payment and project administration remain within Guru and SafePay.
