We’re hiring a part-time Senior PHP / Laravel Developer to work on a production healthcare appointment-scheduling platform. This is a Laravel MVC, server-rendered application with complex domain logic covering providers, services, availability, and insurance, plus integrations with a practice-management system.

The platform handles PHI and supports multi-step booking flows, so security, correctness, and reliability are critical. This is not a SPA — it’s a mature Laravel application enhanced with JavaScript to support dynamic user interactions.

Core Responsibilities

• Develop and maintain Laravel MVC components (controllers, Blade views, Eloquent models)

• Build and support complex booking workflows:

  • Provider and service availability

  • Multi-step form validation and submission

  • Insurance and private-pay logic

• Maintain and extend legacy routes and URL patterns safely

• Integrate with external practice-management systems (read/write appointment data)

• Implement transactional logic to prevent race conditions and double-booking

• Support server-rendered UI with JavaScript (jQuery or vanilla):

  • Dynamic dropdowns, calendars, and time-slot selection

  • Responsive, accessible, form-heavy user flows

• Handle PHI securely using proper validation, CSRF protection, and session management

• Deploy and support the application in a Linux environment (Apache/Nginx, PHP-FPM, MySQL)

• Debug and resolve issues in a live, user-facing production system

• Incrementally improve and modernize the codebase without breaking existing behavior

Required Qualifications

• Strong PHP 8.x experience

• Deep Laravel expertise (routing, controllers, middleware, Blade, Eloquent, migrations)

• Experience building and maintaining server-rendered applications

• Solid HTML, CSS, and JavaScript skills (jQuery or equivalent)

• MySQL/MariaDB experience with transactional data models

• Strong debugging skills in complex, stateful workflows

• Comfortable working in established, non-greenfield codebases

• Security-minded approach to handling PII and PHI

Nice to Have

• Experience in healthcare, scheduling, or booking systems

• Experience with React

• Experience refactoring or stabilizing legacy Laravel applications

• Familiarity with queues and background jobs

• Understanding of concurrency issues in booking systems

• Exposure to localization or translation toolin

How You’ll Be Successful
