• Monitor application performance, identify bottlenecks, and implement optimizations.

• Enforce security best practices (OWASP, secure authentication flows, data protection, GDPR compliance).

• Collaborate with cross-functional teams to translate business requirements into technical solutions.

• Mentor junior and mid-level developers through code reviews and technical guidance.

• Contribute to technical decision-making, challenge requirements constructively, and promote best practices.

REQUIREMENTS

• At least 5+ years of professional experience in software development

• Expert-level knowledge of PHP 8.x and modern development practices

• At least 5+ years of experience with Laravel or Symfony, including deep framework understanding

• Strong experience with MySQL or MariaDB (query optimization, schema design, normalization)
