Dear Hiring Team,

I am excited to apply for the Backend PHP Developer position at CapsLock. With over 4 years of professional experience in PHP development, including extensive work with Symfony and SQL databases, I am confident in my ability to contribute to your marketing solutions platform.

In my previous role, I successfully designed and implemented scalable software architectures, collaborated with cross-functional teams, and improved system performance. I am particularly drawn to CapsLock's remote-first culture and emphasis on written communication, which aligns with my proactive and autonomous work style.

I look forward to bringing my technical skills and problem-solving mindset to your team. Thank you for considering my application.

Sincerely,
[Your Name]

Can you describe your experience with Symfony and explain how you would structure a new project using its best practices?
I have 3+ years working with Symfony, leveraging its bundles, Doctrine ORM, and Twig templating. For a new project, I would start by setting up the Symfony Flex project, define entities and relationships, use services for business logic, and implement security with Symfony's security bundle. I also follow SOLID principles and include unit tests.
How do you handle database performance optimization in a high-traffic application?
I analyze query performance using EXPLAIN, index optimization, and caching mechanisms like Redis. I also implement query batching, use read replicas for SELECT queries, and ensure N+1 query problems are avoided by eager loading associations.
Describe a time you designed software architecture for a complex system. What considerations did you take?
I led the architecture for a multi-tenant SaaS platform, focusing on separation of concerns, scalability, and maintainability. I chose a modular monolithic approach with clear bounded contexts, used event-driven communication between modules, and implemented database sharding for tenant isolation.
How do you ensure code quality and maintainability in a remote team environment?
I advocate for code reviews, static analysis tools (PHPStan), and automated testing (PHPUnit). I also emphasize clear documentation and follow semantic versioning. Regular team syncs and pair programming sessions help maintain consistency.
Explain your experience with Docker and how you use it in development and deployment.
I use Docker for consistent development environments, defining services for PHP-FPM, Nginx, MySQL, and Redis in docker-compose. For deployment, I build optimized images with multi-stage builds and integrate with CI/CD pipelines for automated testing and deployment.
