About this role
JavaScript, CSS, HTML5, Node.js, Database Development, React.js, JSON, Web Development, Frontend Development, API Integration · I’m ready to take my existing web application up a notch by adding an in-app, drag-and-drop layout builder with fully customizable buttons and sections. The goal is to let any non-technical user rearrange pages, create new ones, and tweak component styles—colors, shapes, icons, animations—on the fly, all from the browser.
You’ll work against the current codebase (React + Node) and are free to lean on Claude for rapid prototyping or refactoring as you see fit; I already have an API key available. Expect to add reusable components, a live preview canvas, and a simple JSON schema that persists layouts to the database.
Key deliverables • A responsive drag-and-drop editor that snaps to a 12-column grid • A set of pre-built, theme-aware buttons/blocks the user can re-style without code • State management wired so changes are auto-saved and instantly reflected in preview • Clean, documented code plus a brief walkthrough video highlighting new modules
Acceptance criteria 1. I can build a page from scratch using only the editor—no manual code touches. 2. All created pages render consistently across Chrome, Firefox, and Safari. 3. Lighthouse performance score ≥ 90 after your
