React Ecosystem

Overview

I build production frontend applications using React and its surrounding ecosystem, from React 18 components mounted into Rails monoliths via react-rails, to React 19 standalone PWAs deployed on Cloudflare Pages, to React 19 + Phaser 3 hybrids running interactive WebGL canvases. My work includes clinical-research dashboards, patient-facing decision aids, gamified safety-training simulations, and real-time admin tools.

I focus on architecture, maintainability, and seamless backend integration.

In production

  • Clinical-research admin dashboards: React 18 mounted into Rails via react-rails for a multi-year aphasia-rehabilitation study (50-100 SLPs and social workers) and a psychiatric research study (50-100 clinicians), with Recharts time-series visualizations and Foundation-based modal flows.
  • Patient-facing clinical decision aid: React 19 SPA implementing multi-cohort Cox-survival risk models in JavaScript, with a <1% probability guard for clinical correctness and an unlockedNavItems Redux slice for linear page-gating across a privacy-first all-local-computation architecture.
  • Gamified WebGL safety training: React 19 shell + Phaser 3 game canvas for a home-healthcare-worker safety-training tool with hundreds of active users. A single Redux store bridges the React HUD and the Phaser game loop; a parallel DOM accessibility overlay makes every WebGL hazard reachable by keyboard and screen reader.
  • Child-development research PWA: React 18 + Create React App on Cloudflare Pages with devise_token_auth rotating headers handled centrally in the root reducer and per-action header injection via an Axios interceptor.
  • Behavioural-change RCT: React 18 islands inside a HAML/Rails application, with per-module BrowserRouter-driven assignment flows that branch on persisted form values for study-protocol-specific question paths.

Problems Solved with React

1. Scalable Component Architecture

I design reusable, modular component systems that:

  • Promote code reusability
  • Reduce duplication
  • Support long-term maintainability
  • Enable scalable UI systems

Using functional components and hooks, applications remain flexible and performance-oriented.

2. Predictable State Management

For complex data flows, I implement:

  • Redux and Redux Toolkit
  • Context API for lightweight global state
  • Optimistic UI updates
  • Server-state synchronization strategies

Ensuring consistent, debuggable state behavior across large applications.

3. Performance Optimization

As applications grow, rendering performance becomes critical. I optimize using:

  • Memoization strategies
  • Lazy loading and dynamic imports
  • Route-based code splitting
  • Bundle analysis and optimization

Performance is treated as an architectural decision, not an afterthought.

4. Data Integration & Real-Time Updates

I integrate:

  • REST and GraphQL APIs
  • Token-based authentication flows
  • WebSocket-based real-time updates
  • Error boundaries and graceful fallbacks

Ensuring resilient, responsive frontend systems.

5. Accessibility & Maintainability

I prioritize:

  • WCAG-compliant accessibility
  • Responsive design patterns
  • Testing with Jest and React Testing Library
  • Clean linting and formatting standards

Creating frontend systems that are both robust and user-focused.

Why React?

React enables component-driven architecture, predictable state management, and scalable UI systems, making it ideal for complex, data-driven applications.
