- Logic & Runtime: Work with Node.js for specialized microservices, real-time data processing, or internal tooling.
Frontend & Integration (The “Plus”):
- Full-Stack Collaboration: Partner with UI specialists to integrate backend logic with React frontends.
- Component Maintenance: Modify or build React components to ensure end-to-end feature delivery.
- JS Ecosystem: Use your JavaScript knowledge to ensure seamless data flow between server-side services and the browser.
Performance & Reliability:
- Optimization: Identify and resolve bottlenecks in the backend, from complex SQL queries to inefficient PHP processing.
- Testing: Maintain a rigorous testing culture, writing unit and integration tests (PHPUnit) to ensure platform stability.
- Security: Follow “security-by-design” principles across the stack, focusing on data protection and secure authentication.
Qualifications
- Experience: 5+ years of professional backend-heavy development within a team environment.
- Mastery: Deep expertise in PHP 8, Symfony, and MySQL.
- Database Variety: Hands-on experience working with MongoDB in production.
- Full-Stack Competency: Functional proficiency in React and Node.js.
- Tooling: Proficient with Git, Docker, and working within modern CI/CD pipelines.
