Remote US React Developer — overview
Sharon Rosario builds React interfaces that are fast, accessible, and maintainable — not just visually polished. That means components with clear boundaries, a state model that does not fight the framework, performance budgets that keep Core Web Vitals green, and accessibility built in rather than audited in later.
Because Sharon is full-stack, the React work is never disconnected from the data behind it. Streaming responses from an AI backend, optimistic updates, and real-time UI over WebSockets are built with an understanding of the API and infrastructure on the other side — which is where most frontend-only developers get stuck.
Modern React, done properly
React 19 and TypeScript, with Next.js or Vite depending on the project. Tailwind for styling, sensible state management (Context, Redux, or lighter tools where they fit), and Suspense-based code-splitting so the initial load stays lean.
Accessibility is a first-class requirement: semantic markup, keyboard navigation, ARIA where it is actually needed, and respect for reduced-motion preferences.
Frontends that talk to real backends
Sharon has built React frontends that stream tokens from LLM backends over WebSockets and handle long-running, event-driven jobs without freezing the UI — see the event-driven microservices case study below for the full frontend-to-backend picture.

React 19 with TypeScript, Next.js or Vite, Tailwind CSS, and state management chosen to fit the project — Context, Redux, or lighter alternatives. Code-splitting, performance budgets, and accessibility are standard, not optional.
Yes. Sharon is a full-stack engineer, so the React work connects to APIs, databases, and real-time infrastructure that Sharon can also build — including streaming AI responses over WebSockets.
Accessibility and performance are built in from the start: semantic HTML, keyboard support, ARIA where appropriate, reduced-motion handling, and performance budgets to keep Core Web Vitals healthy.
