Contract Full Stack (React Focus) Web Developer

Senior-level full-stack web developers with approximately five or more years of experience, especially those focused on React and comfortable working remotely with partial US business-hour overlap, are best suited for this role.

Required skills include React, WordPress development with custom plugins and integrations, PHP, MySQL, JavaScript, HTML, CSS, Git, REST APIs, and GraphQL.

Candidates should be familiar with iterating on existing applications, improving user interfaces and layouts, building WordPress content-management features, connecting data and systems, troubleshooting complex problems, and collaborating through regular feedback cycles.

How would you structure a React application to support iterative UX improvements and maintainable feature development?

I would organize the application around reusable components, clear feature boundaries, and predictable state management. I would also establish consistent patterns for routing, API access, form handling, and testing so the prototype can evolve without accumulating unnecessary technical debt.

How would you improve the performance and user experience of a React application?

I would measure performance first using browser tools and React profiling, then address issues such as unnecessary re-renders, oversized bundles, slow API calls, and inefficient lists. Techniques could include memoization, lazy loading, code splitting, caching, and accessible loading and error states.

How would you integrate a React frontend with a REST API?

I would create a consistent API layer for requests, authentication, validation, error handling, and response normalization. Components would consume this layer through reusable hooks or services, with appropriate loading, empty, retry, and failure states.

When would you choose GraphQL over REST, and what challenges would you consider?

GraphQL is useful when clients need flexible, nested data or when reducing multiple frontend requests is important. I would consider schema design, query complexity, caching, authorization, error handling, and avoiding over-fetching or inefficient resolver implementations.

How would you extend WordPress with custom functionality for a React-based application?

I would build functionality in a custom plugin rather than modifying the theme or WordPress core. The plugin could register custom post types, taxonomies, metadata, REST or GraphQL endpoints, permissions, and data validation while keeping the integration modular and maintainable.

How would you design WordPress data structures for content consumed by React?

I would model stable concepts as custom post types or taxonomies and use structured metadata for related fields. I would expose only the required data through documented endpoints, validate inputs, enforce capability checks, and plan relationships to avoid difficult-to-maintain queries.

How would you securely implement a custom WordPress REST API endpoint?

I would register the endpoint with strict argument validation, sanitization, permission callbacks, and appropriate authentication. I would also restrict returned fields, use nonces or another suitable authentication mechanism where applicable, and ensure database operations use WordPress APIs or prepared queries.

How would you use PHP and MySQL when implementing custom WordPress features?

I would follow WordPress coding conventions, use hooks and established APIs, and keep business logic separated from presentation. For MySQL access, I would use the WordPress database abstraction layer, prepared statements, indexed fields where needed, and migrations for any custom tables.

What Git workflow would you use for a project with two-week feedback and revision cycles?

I would use small, focused branches with descriptive commits and pull requests that are easy to review. Each change would include testing notes and, when appropriate, screenshots or reproduction steps, while the team would use the agreed branch strategy and continuous integration checks.

How would you approach accessibility and emotional-safety considerations in an application about conflict and self-awareness?

I would follow WCAG principles through semantic HTML, keyboard navigation, visible focus states, sufficient contrast, accessible forms, and screen-reader-friendly feedback. I would also use clear, non-judgmental language, predictable interactions, privacy-conscious data handling, and carefully designed error and escalation messaging.

Join an established, fully remote digital team with more than a decade of experience, recognized as a Best Place to Work, to help build an app that strengthens self-awareness and emotional intelligence. You’ll develop and refine the React-focused user experience, extend WordPress content management functionality, and integrate APIs while collaborating with the project team once or twice weekly. The stack includes React, WordPress, PHP, MySQL, JavaScript, HTML, CSS, REST APIs, GraphQL, and Git; this is a full-time, part-time, or contract role requiring at least two hours of overlap with 9–5 p.m. ET. Compensation is flexible and may be hourly, project-based, or structured around 20–40 hours per month, making this a meaningful opportunity to create positive impact with a supportive global team.
